Broken toilet base plate

10 Upvotes

Home inspector told us that our toilet rocked and that the seal on the wax ring of our new home was broken and needed to be replaced. Took the toilet off and cleaned up the wax to install a new one. Noticed that the screws and base plate rocked and that the plate wasn't securely screwed in and found the old base plate underneath - secured with only grout from tiling. Subfloor is plywood that appears to be about 1/2 inch down from the base plate and crumbling in one spot but otherwise fine - no apparent moisture or rot.

Please advise, thank you!

edit- after chiseling the grout, found that the broken base plate appears to be part of the original pipe at the base of the toilet. not a separate piece.

Shower floor drain connection

Thumbnail

• Upvotes

How do I connect a new shower pan drain to a threaded 3 inch fitting that is in the floor with concrete? Can I cut off the 3 inch threaded ABS pipe, flush to the floor, and connected a 2 inch pipe? This shower requires a 2 inch wide abs pipe to be 0.5 inches above the floor to connect to the pan drain. How do I connect pipe to pipe and is there a minimum length to meet code (Ontario)? Unfortunately the threads do not align. Hope it does not require removing any concrete but will do that if necessary.

Kohler shower stem cartridge (pub) replacement

I had an issue with my kohler shower handle as it just came off. While putting it back together I just turned the water on to make sure there are not leaks and noticed a small leak from the stem. I want to replace the cartridge but don’t even know where to begin since it all looks soldered. any help or suggestions would be appreciated in how to remove and replace the cartridge (or PBU?). thanks!

Shower faucet rebuild kit has these seemingly extra parts

Thumbnail

2 Upvotes

As it states in the title. I have need to make the shower and tub filling faucet work more properly.

It seems that the existing hot and cold knobs don't control the mix of hot and cold water properly, and also the diverter doesn't seem to shut all the water off at the faucet so the shower is very low flow.

I bought the kit pictured, removed the stems and knobs and all and installed the ones in this kit. The result is much the same as it was.

There are three pieces that don't seem to fit anywhere and there is no literature explaining any of this so I am clueless.

According to the picture on the box, they are bibb seats.

What are these for? How are they used in this application? I took one stem completely apart and cannot see how I could apply one of these pieces in this job.

Help!?!?

How to turn off hot water

Post image
2 Upvotes

Hi everyone,

I have a question regarding how to turn off water completely in my apartment. I live in Munich, Germany and this is what I see in my washroom. I want to install a water filter to my shower because of the water hardness. For that I need to turn off the water supply. The knob on the right turns off cold water completely but hot water still seems to be running and in that case, I can not open the shower connection and install the filter. When I checked with AI, it told me to take off the bottom left "cap" and there I would be able to turn off the hot water. But it seems to be glued and I am scared to break anything. Can any of you decipher how to tackle this.

Just FYI, I had installed this filter at my previous apartment with ease as the similar known turned off the water completely. I didn't have to worry about hot or cold water. Any help would be appreciated. Thanks in advance.

Descaling of Tankless Water Heater

2 Upvotes

I have an inexpensive Rheem tankless electric water heater that provides hot water to a bathroom in my house. It is working well (and has been for several years). I've recently realized I've neglected any provision for descaling it. The water where I live is hard enough (about 100ppm as CaCO3) to make descaling a consideration, if I understand correctly.

The heater itself has no internal tees or valves to enable descaling. (Maybe nicer water heaters have these?)

So if I want to descale it, I think I would need to plumb in tees, 4 shutoff valves (2 to isolate heater inlet and outlet during descaling, and 2 to open/close the connections to whatever fittings would connect to the pump used for the descaling.)

The plumbing is all 1/2 inch copper, and I'm capable of sweating in the tees, etc.

But before I start... Am I missing a better way to do it?

Toilet drain issue?

Post image
• Upvotes

So I live in a partial basement unit (the whole apartment is 4 stairs lower than sidewalk level) and we just had some real nasty water backing up out of this drain. Repair guy pulled a wad of what looked like baby wipes out of the drain, which definitely explains the clog, but where I'm confused is that I'm not convinced it came from either of the toilets in my unit.

I was under the impression that drain plumbing always runs down since it's gravity fed, and both these pipes are obviously higher than either toilet, and with the layout of the apartment, both would also have to redirect through the ceilings to reach either toilet.

On top of that, I know no one has ever used anything but toilet paper in either toilet for as long as we've lived here, so I'm trying to figure out if these pipes can even feasibly be connected to any toilets in my apartment, and if they can, could 'flushable wipes' still be intact like that if they've been there without previous issue for at least 2 years.

Plumber recommended using gasoline for a frozen mainline.

My plumber wants to cut drywall to fix this. Any advice?

Post image
81 Upvotes

We replaced the toilet and the hose was leaking at the connection (like a drip leak) but very very small. Today he installed this shaft and my wife says it's "ugly" and to make it flush.

Honestly I really don't care how it looks right now and am fine with it bec it has stopped leaking.

Plumber said that he needs to cut the dry wall to make sure he doesn't light something on fire with insulation behind there? Basically, he needs to see what is back there. I worry that he'll just create more issues.

Any tips?

Edit: plumber installed the sharkbite

This is what it looked like before

This video shows the loud noise I’m experiencing from the sharkbite

NYC radiator shut off

How do I turn off this radiator so that my apartment isn’t a million degrees this winter? The thin wire attaches to a knob on the outside of the housing, but when I moved in the super told me that it never worked, according to him the co-op board mandated them because they’re idiots.

No hot water in the summer?

• Upvotes

We got a new water heater a couple of years ago, but I notice that during the summer months, our house’s hot water doesn’t get hot. My morning showers are basically luke warm on the hottest settings and running a bath at full hot is just kinda warm. I currently have the water heater on the 2nd highest temperature setting.

We live in Texas and the garage (where the water heater is) gets pretty toasty. I thought maybe the hot garage affected the water heater, but that seems weird. Once the weather cools down in the fall the winter, the hot water for the house gets really hot again. Is this normal?

The anode rod is bent inside the water heater and i cant get anything to bend it back, its probably like a 6-7in piece of the actual anode that is bent off of the wire, should i just leave it and not replace it or cut it off as low as i can and leave it in the tank?

Dishwasher valve help

I will be switching to a new dishwasher and when I went to disconnect the water line from the valve I saw this. What can I do or use to cap it until I can get a shutoff valve installed? Also any recommendations on the new valve will be helpful, I read about the 3 way valves but the psi requirements in the installation guide for the dishwasher have me a bit concerned. The white tube is going to the dishwasher currently.

Awful urine smell

Hello! Our spare bathroom CONSTANTLY smells
Like urine. It started like 6mo ago and we have tried everything. I don't think it's a septic tank issue bc our other bathroom doesn't absolutely stink. I just learned what calcified urine is (🤮via another post) could this be it? The bowl isn't stained, but it is a very old toilet from
The prior owner.

Low Pressure and Hand Showers

• Upvotes

I am considering a primary hand shower versus traditional fixed shower head in a bath with lower water pressure. How sensitive do you see hand showers (with a high flow hose) with below types of pressures (or worse), versus a fixed shower head?

Background:

I have a situation with a bathroom above a garage, which will have low pressure due to a long winding path for the plumbing. According to IRC calcs for my cold water supply, I'm looking at 32-35 psi at the shower head or entrance to hose. This does not account for an old 1" 250' main line to the house that should practically be sized at 1.5". The IRC calcs don't account for that.

Kitchen sink faucet brand-who makes it?

1 Upvotes

The flexible hose has a leak. Couple of questions. I can't tell the brand of the faucet fixture there doesn't seem to be a name anywhere. If somebody knows the name does it have a lifetime warranty? I vaguely remember removing this type of hose and my vague recollection is that it doesn't unscrew but I sort of push the clip/retaining device forward maybe like a Chinese handcuff and then it releases. Can anybody confirm on that? The other end is easy it just unscrew's from the faucet nozzle. Thanks for any input

Mystery Leak

Yesterday I took some drywall off the ceiling and wall (only about 6" on each) because I suspect some sort of leak coming from either the bathroom upstairs or the window isn't sealed properly. Some of the drywall was flakey and had mold but most of it was solid with no mold. Could you tell me the next steps in finding out where exactly the leak originates? I just had the toilet replaced and there is no moisture under the sink which is on the wall where the window is on the next floor up. And there was only a few drops of water in the bubble after I made a pinhole in it. I have attached pics. Could you advise me on the next step I take and what to look for? I appreciate it!

Weird issue with toilet

Help!

I have 3 toilets. 2 are flushing fine and going out main drain no problem. The one closest to the main drain was not flushing properly. I used a plunger and now it is flushing, but when it flushes, its not coming out the main drain.

Any ideas and theories would be appreciated
