More Dry Walls Down – Performing Open Surgery on Our Utility Room

Who would knew this little laundry room in our basement has gotten most of our attention? Our bedroom only got a bed, the living room does not even have a sofa yet, and Slav’s office has been a dump ground for all the books and magazines. But this little laundry room, boy, has renovated changed 100%! We sacrificed a whole bedroom to return its old glory, we have installed a new HVAC, and everything else in the room has been replaced, including the furnace, the washer and dryer, and most recently, the water heater.

IMG_6902

Above was the laundry room when we bought the house, you can see the old washer and dryer combo to the left and the purple bedroom to the right. Below was after we combined the purple bedroom and the laundry room to make a “new” utility room.

IMG_9064

Before we could even do a load of laundry in our new utility room, the old water heater went out. Slav installed a new tankless water heater which marks the last appliance replacement in the room – at this point, every single thing in the utility room is added/replaced by us. However, the pipes and connections hidden in these walls are still old, and we were 99% sure that some of them were leaking. So Slav said, what the heck, let us open it up and straighten things out!

IMG_9443

I knew that I’ve praised Slav on this blog before, but this man is really my hero. He has worked for the entire week prior since the water heater broke, and I can tell that he has had enough of this room. But Slav is also a guy who always does the right thing. Regardless if it is work, or life, I have never seen him taking a shortcut, or trying to get away from his responsibilities. He knew that the pipes and connections behind the appliances must be a mess, and that is what brought him back to this room to take down these walls.

And this is what the room looks like now. How could I not praise this man?

IMG_9459

To understand everything Slav did back there, let us go back to the same wall a couple days ago, right after the new water heater was installed:

IMG_9357

1. Getting rid of the partition wall and soffit

As you can see, there was a wall between the laundry units and the water heater. There is also a soffit above the laundry units. The clear pipe held by metal clips connects the condensation pump to the washer drain, which drains our HVAC, furnace, and water heater.

IMG_9360

We decided to tear down the partition wall, dry wall and the soffit entirely. We knew what’s behind the soffit – our dryer vent. But we still want to open it in order to fix the neighboring bathroom vent behind it. We suspect that the bathroom fan vents directly into the wall, instead of carrying moisture outside of the house. It can produce mold in the walls, and need to be fixed before the bathroom can be used regularly. Without a clear renovation plan, we’d rather not open up any walls in the bathroom, so it makes a lot more sense to open up the soffit in the utility room to troubleshoot.

What made things easier is that the bottom half of the drywall here was already missing.

IMG_7426

See the wall cavity between dryer vent and the washer? That is the inside of our bathroom vanity. Yep, you can put an arm through the wall, open the vanity door, and grab someone’s leg when he/she washes hands in the sink. It will be the best Halloween scare ever.

So Slav went to town and removed the partition wall (not weight bearing), the soffit and the dry wall in between. Now we could see all the connections, and things were messy:

IMG_9445

For one, the water lines feeding into the washer were not fixed to the framing. The connections are supposed to be bolted onto studs to prevent water pipes from vibrating when water comes in, which could cause leaks at distal connections.

Behind the dryer, the vent pipe was a mess. It consists of three different sections, all in different material, and they are only loosely attached to each other.

IMG_9446

And it is definitely snapped open in the middle, which means some of the hot and moist air was pumped into the walls whenever the dryer was in use.

IMG_9447

Slav peeled off the dryer vent completely to reconnect the pipes properly. See the duct tape on one section? Oh boy.

IMG_9457

2. Switching/Reconnect Merry and Pippin

I have requested to switch Merry and Pippin around, so their doors can open to each other, instead of against each other. So Slav dragged them out, vacuumed clean between the studs, and relocated Pippin (the dryer) to the right side and Merry on the left.

Since Pippin is now next to the exterior wall, Slav shortened the dryer vent pipe and mounted it neatly:

IMG_9482

IMG_9474

See the bath tissue between Merry and Pippin? Hello bathroom vanity!

IMG_9476

Everything is taped shut and properly secured to the framing:

IMG_9471

The washer water lines are cleaned and reconnected as well.

IMG_9467

IMG_9470

Ans this is what Merry and Pippin looks like today – how neat!

IMG_9464

3. Fixing the bathroom vent

As expected, we got to peek into the bathroom soffit from this side. This is the view of bathroom vent pipe, and it was – wait for it – not connected to the bathroom fan at all.

IMG_9448

With sufficient lighting from the utility room, you can also see the pipe from the bathroom too.  Yes, there is a hole at the bottom of soffit, directly above the shower. And no, we did not make the hole. It came with the house.

IMG_9454

Slav reconnected the bathroom vent pipe to the fan and clamped down the connection. Now our bathroom fan is venting to the outside as it is supposed to, and no moisture, either from the dryer vent pipe, or from the bathroom fan, will accumulate in the wall anymore. 🙂

IMG_9478

The Current Utility Room

After 6 hours of work, this is the “new” new utility room we now have:

IMG_9459

I love how clean, and organized this room is. Everything works and there is no mystery. We plan to keep the utility wall open like without drywall over, which makes it a lot easier to renovate the bathroom down the road. For appearance, we might build a closet to conceal all the appliances down the road. But for now, we are enjoying the easy access and clean sight. No other room in this house gives me such sense of proud, victory, and peace – we own it, 100% – our “new” new utility room!

 

 

Installing a New Tankless Heater

Meet the beauty, who now lives in our home:

IMG_9274

And here she is, undressed:

IMG_9285

The other side of the room however, now looks significantly worse:

IMG_9256

IMG_9284

With PVC dust that is impossible to clean:

IMG_9367

Following the breakdown of our water heater last Saturday, we got the insurance company straightened out and the old water heater pushed aside. We decided to cash out of insurance claim and invest it towards a tankless water heater. To save some $$$, Slav decided to install it himself.

Wednesday night, Slav and I went to Lowe’s and picked up the only gas tankless water heater they have in stock, along with a few supplies. It had been five days without hot water at this point; the cold showers really motivated us to push forward.

IMG_9268

Slav did some research and determined that the Rinnai one Lowe’s has in stock is sufficient for our house. It has 7.5 gallon per minute output, which supplies a couple sinks and appliances (washer, dishwasher, etc) and a shower at the same time. It has temperature settings from 120 degree to 150 degree, which is similar and above the temperature we have set our tank heater in the past (~125 degrees). This unit also qualifies us for $100 X-cel energy rebate being high sufficiency (>90% energy factor), and we received a tax-free wavier from the Arvada city hall for purchasing it locally.

IMG_9272

The water heater is $899 in Lowe’s now. With all the rebate ($100) and tax waiver, this unit now costs us only $800. We are getting about $550 from our insurance company, and Slav is installing it himself with a permit ($69) from the city. So for the heater itself, the price is about $320. We did need a bunch of fittings and PVC pipes, which cost a couple hundred dollars in total, but with tons of left overs for future projects. In the end, I think we are paying out-of pocket ~$500 for this heater.

IMG_9276

The two metal pipes ($10 each) on the right are for cold and hot water. Slav also purchased a pair of isolation valve ($99) to connect them to the water heater. The yellow pipe at the bottom (similar) is for gas. We could use black iron pipe, but this flexible pipe makes the final 2 feet of connections much easier. We bought 25 feet and the leftover pipe will be used to connect the future gas stove in our upstairs kitchen.

IMG_9275

IMG_9277

Slav also bought some PVC pipes and elbows for fresh air supply and exhaust. The building codes dictate how long the PVC pipes could be between the heater and outside, and the use of any elbow will count towards the length. Therefore, it is important to check the installation manual and local building codes to make sure that the heater is not installed too far away from an exterior wall. Our ranch is very narrow, so it is not a problem for us to install the heater right at where the old one was.

Slav opened up the ceiling a bit more to make the PVC pipe installation easier:

IMG_9282

IMG_9281

And he worked through Thursday to install the heaters on the wall:

IMG_9285

Our initial plan was to fit in an utility sink underneath, but unfortunately, the installation manual and building codes prevent us from mounting the heater any higher. I guess we would still do an utility tub if we want to.

IMG_9290

The heater is connected to the cold and hot water lines and the gas line from the bottom. The yellow flexible gas line is connected to the black iron gas pipe with a shut-off valve:

IMG_9293

It is a big upgrade from our old gas line, which is no longer up to code in our city:

IMG_9295

Later on, we learned that by code, we needed to establish electrical continuity between the black iron pipe and the new flexible metal pipe. So Slav connected the piece of copper wire between them using two clamps:

IMG_9375

IMG_9348

The clear pipe coming out of the heater is for condensation. Tankless water heater like ours requires two condensation pipes, one from the heater itself and the other one from the exhaust pipe. You can see in the picture below a skinny PVC going straight down from the exhaust pipe to the condensation pump.

IMG_9374

We installed this condensation pump during the HVAC installation. It has four receiving ports, one for AC and furnace, the other two are occupied by the heater. This pump is connected to the washer drain, which directs any condensation down the floor drain in the utility room.

IMG_9286

The cold (blue) and hot (red) water lines are connected to the bottom of the water heater, with the two isolation kits in between. The isolation kits are technically not needed – you can connect the hot and cold water pipe directly to the heater. But they make future diagnose and maintenance a lot easier. The side valves on these isolation kits function as drainage and an access point for flashing the heater, which is a recommended yearly maintenance.

The copper pipe on the side of the hot water isolation valve is an emergency valve. If there is a buildup of hot water for some reason, this valve will open itself with certain pressure to let the hot water out, so we are not risking an explosion. We are not sure at this point where we should connect it to yet, a question for our inspector.

IMG_9378

Connected to the top of the heater are fresh air supply and exhaust, which are two 3 inch PVC pipes.

IMG_9349

They are directed away to the heater, running parallel to the PVC pipes of the furnace:

IMG_9340

IMG_9342

These pipe runs out of the back of the house, from the opening of the old fresh air supply:

IMG_9343

IMG_9312

Slav mirrored the furnace pipes. Now it looks like an art! A metal panel leftover from our furnace was cut out to cover the hole on our brick:

IMG_9335

One of the good outcomes from this installation is that the exhaust vent is no longer needed. It actually came out of our roof, which was just reinstalled. It could be covered if the water heater was down just two weeks early! Oops!

IMG_9297

The real advantage of removing the pipe is to save space in the neighboring bathroom. See the triangle shape of soffit on the very right corner? It encloses the exhaust pipe you see in the picture above.

IMG_9299

We think the big bump next to it is for accommodating the exhaust pipe as well. We are pretty sure by this point that there are two pipes behind the soffit in the bathroom and the utility room above the washer and dryer, which are for the bathroom vent and the dryer vent. But these pipes are not supposed to take so much space.

IMG_9300

IMG_9298

We hope by capping the exhaust pipe and opening up the soffit in these two rooms, we can consolidate the pipes to make at least the soffit in the bathroom disappear. That will add so much head space in the bathroom!

With the momentum going strong in the basement, Slav is opening walls left and right in the utility room. 🙂 I am looking forward to showing you what we’ve found after the cleanup!

Our Water Heater Breakdown – Attack from the Within!

Our October goals, originally, had nothing to do with laboring in the basement. We want to hike with our pups, watch leaves changing colors, watch ski movies, and hit thrift shops and flea markets. We will still work on the ranch, but after replacing the roof, grading around the house, and caulking every seam inside and out, we were done thinking about anything water-related. For heaven’s sake – I typed the phrase “water-proof” so many times that my browser now auto-completes it for me!

Just when we thought we were done with water. Water is not done with us. Last Saturday, in a bright, sunny morning, our basement flooded:

IMG_9217

We had done so much to protect our house from water coming from the outside, and did not think that we could get water from within. Yep, it was the water heater – the last piece of major utility appliances we had not replaced:

IMG_9251

Fortunately, we have a floor drain nearby and the leaked water went down there. The flood was pretty confined.

IMG_9222

IMG_9235

Slav immediately terminated the gas and cold water supply to the heater, and started to drain the hot water tank directly to the floor drain:

IMG_9246

It was last weekend we opened up the utility room to the neighboring bedroom. Imagine how difficult it would have been to work with the water heater if we have not done that!

We happened to have just purchased a wireless endoscope. It was immediately put in use:

IMG_9239

This endoscope/camera kit transmits signal wirelessly to our phones and tablets. After some probing, Slav caught this video from his phone:

He slowly retracted the probe end out of the water heater, so we could see that the leak is really close to the bottom of the rusted tank reservoir. It makes sense since that is the location with the highest pressure. It also meant that the leak would only stop when all the water was drained out.

IMG_9265

It took almost the rest of the weekend before the tank was drained completely. During this time, we contacted our insurance company. We purchased a separate home warranty for a year, which covers major appliances and plumbing during our first year of home ownership. We got it with the old furnace and water heater in mind. We had replaced the furnace out-of-pocket during HVAC installation, so it is not a bad thing that the water heater went out during the first year of our ownership.

We submitted some pictures and the video showing the leak, and on Monday, the insurance company sent a plumber to complete a report. Our claim was of course accepted, but only for a basic water heater that matches our capacity and labor cost for simple replacement, which added up to merely $500. From the plumber’s quote, we knew that it would not be the actual cost, because codes have changed dramatically since the last water heater was installed 15 years ago. Even installing a new basic water heater would require us to switch tubing and modify the gas line, adding about another $500 which we have to pay out-of-pocket.

Slav called me at work mid-day to discuss all options and our preferences. We decided to get a tankless water heater instead of a standard one. For one, tankless is what we had wanted all along. Second, it will cost us as much as the plumber’s quote, which is about a grand, and Slav can install it himself to save the labor cost. Our insurance company agreed to cash-in, so we are still getting the $500 that would have gone to the plumber, and still paying another $500 out-of-pocket which would have gone to the plumber as well. So we might as well let the $1000 go to ourselves for a new tankless water heater.

When I got home from work on Monday, this was the first thing I saw walking down to the basement:

IMG_9264

The man has clearly done something. Let me tell you – Slav is a very, very, very patient man. He is the most accommodating and gentle person I knew. But there is a limit. This house is clearly pressing his button with the old, rusty water heater. The misbehavior will not go unpunished.

Within a few short hours Monday afternoon, Slav has gotten the insurance company straightened out, gone to the city hall to get a permit for self-installation, gathered codes and manuals for installation, and decided on a water heater to purchase. He also (!) disconnected the water heater and capped the water and gas lines:

IMG_9258

And kicked it out of his way:

IMG_9366

For a high energy efficient tankless water heater, two 3-inches PVC pipes are required to be directly connected to the water heater to supply fresh air and exhaust. Slav removed old supply pipe (labeled with blue arrow in the picture below) along with the exhaust pipe directly above the heater.

HVAC room

IMG_9262

This old fresh air supply pipe came from the back side of the house, went through the ceiling and was parallel to the PVC pipes for the new furnace. You can see it in the pictures below:

IMG_7668

IMG_7666

It came out of the back wall immediately to the right of our furnace PVC pipes, above the window well:

IMG_7678

After we removed the dividing wall last weekend, the pipe was already exposed:

IMG_9140

IMG_9078

So Slav removed it completely to make room for the new 3-inch PVC pipes. In this way, we have both PVCs come out of the house just like the setup for our furnace, and the roof vent can be capped.

IMG_9259

With insurance cash coming in, and permit on hand, Slav started planning pipe layout and getting all the supplies. The man is on the move!
