    Toilets gurgling when showering - partial clog in main line?

    Hi all, Last night I was showering and heard a gurgling sound. I figured out that when I ran the shower that both toilets in the "Jack & Jill" (double) bathroom were gulping air from the bowl. When I tried flushing the toilet, it just filled with water and then slowly drained. I believe this...

    Hi all, I finished my Jack-and-Jill bathroom remodel a while back (thanks to a lot of help from the good folks on this forum!). I installed two new Toto Drake II toilets. They both have the CeFiONtect bowl coating that is supposed to keep the bowl cleaner, longer. I also installed a...

    Pop up lav assembly: sealant on threads and/or gasket?

    Hi all, I recently installed a couple of new lavatories. Everything went well with no leaks. Since then I have seen a couple of videos where the person uses pipe dope on the threads and/or rubber gasket (circled in red in my attached photo). What is the best practice? Do you use pipe dope on...

    Ideas for tricky water heater line routing: crawlspace to slab transition

    Hi all, I recently swapped out all the old 1960s galvanized steel piping in my crawlspace and replaced with Uponor PEX. Unfortunately, there is a small bit of galvanized remaining that runs from the crawlspace wall into the utility room where the water heater is located. The utility room is on...

    Major water sediment problem: any idea what these black flakes are?

    A flurry of posts today...but this one is by far the most important! So today I installed a water pressure relief tank. I did not have one before and kept the water heater temperature at 120F. I just increased it to 140F after installing the pressure relief tank. After the hybrid heater (GE...

    My PRV disappeared! Can the city manage water pressure without PRVs?

    Hi all, About 5 years ago I learned that many homes have a pressure reducing valve (PRV) to control the water pressure to the home. At that time I also discovered that my home's PRV was not operating correctly and needed to be replaced. I replaced it without issue. I am now doing some...

    Amtrol Expansion tank - turbulator does not fit - bad part, or bad instructions?

    Tricky bathroom vanity sink & faucet install: how would you do it?

    Hi all, I have a tricky situation in a bathroom remodel. The original 1960s design had a small wall-hung sink. I have remodeled and changed the wall-hung sink to a small custom-built vanity with an undermount sink. The countertop is quartz. The vanity and countertop is necessarily small to fit...

    What is your preferred sink p-trap?

    Hi all, I'm installing two new sinks. I ran new PVC pipe to both sink locations. Now I'm deciding on which p-traps to install and am surprised at the wide variety that exist. I know I could just pick one and it would be fine - but I'm curious what those with experience prefer. Chromed brass...

    Closet flange will not fully insert into soil pipe - solutions?

    Hi all, I'm about to set a new toilet on a new soil pipe that I recently installed. I installed my soil pipe about a foot higher than the subfloor so that I could later trim it flush after the finished floor was installed. Last night I cut the soil pipe flush with the finished floor. Now I'm...

    Slow leak from shower p-trap during leak test

    Hi all, Thanks to the kind members of this forum I was able to pass my drain leak test (hydrostatic test) this morning! However, after the inspector left, I noticed a tiny, slow leak at the shower p-trap swivel nut. I have attached a photo which shows the fitting and some drips of water coming...

    Does the orientation of a supply tee matter for water flow rate?

    Hi all, I am installing my shower valve and volume controls and need to use a tee to split the supply after the thermostatic valve to provide service to the shower head and hand shower. Does the orientation of the tee matter if I want the shower head and hand shower to have the same flow rate...

    Replace lower section of cast iron plumbing stack with PVC: good idea, or not?

    I'm currently doing a bathroom remodel on a 1960s home. The horizontal cast iron drains in the crawlspace were replaced a while back with PVC. The plumbing stack transitions from PVC in the crawlspace to cast iron which exits the roof. Just above where the plumbing stack transitions from PVC in...

    Lavatory drain stub out - are fernco couplings considered a "hack" job?

    Hi all, I'm remodeling my 1960s bath with two sinks. The current drains use copper adapters connected to the cast iron plumbing stack. The copper portion will stick out of the finished wall about 1" and there is a chromed steel pipe attached to that. I have attached a photo. I was planning on...

    Bath remodel floor rot - problem or not?

    Hi all, I am remodeling my 1960s bathroom and just removed the old bathtub. I discovered some rot on the floor sheathing and beams as a result of a leaking tub drain (I think). It appears that a repair was attempted at some point but now that the old floor and tub are gone you can see the full...

    Bathroom vanity remodel: drain and supply line heights

    Hi all, I'm currently doing a bathroom remodel. It seems that the standard is to install the supply lines higher than the drain line - but is this necessary? If so, why? Is it a code issue or just convention? I currently have my supply lines lower than the drain line - I've attached a photo...

    PVC primer & glue dauber size - a dumb question?

    Hi all, Maybe this is a dumb question because a search on the forum suggests it hasn't been brought up before! I was reading through a MFR's guide to solvent welding PVC pipe and noticed that they strongly recommend that the applicator (dauber, swab, etc) should be sized at least 1/2 the...
