Replacing a sink at home. Looks like the sink drain line is too short. Bit of a novice at this stuff, should I get a longer P-trap, or splice together some PVC or something?

How are spigots/plumbing measured?

I want to replace a garden spigot that has damaged splines to where the turn handle would be attached. How do I measure correctly so that I could go to a parts store once? The spigot in question has a male thread to the source pipe. I measured the spigot's inlet as 1 1/16" OD on the thread. I also measured the ID as 5/8". I'm assuming the ID is the correct measurement for the proper replacement. Is there anything else I need to know to size it correctly?

Also to add, my house was built in the 50s if that helps.

Can a generator hookup (with a lockable valve) be added here? Not trying to do it myself - I just want to know what's possible before I talk to a pro.

The generator needs 135,000 BTU/hr.

Can someone help with a Bottlebrush stuck in pipe?

The sink in my kitchen is clogged and I had no Idea what to do,I came up with the brilliant idea to put a bottlebrush in the pipe and now it's stuck inside. I tried to get it out with force and with twisting it, but no chance. A plumper would be about 300€, what should I do. It's a plastic pipe, would you suggest to cut it and replace it with another. The pipe is not moveable as it is a part of the wall.

Home sprinkler system leak - regular plumbing job or specialist needed?

A friend is buying a house in Philadelphia and the inspectors report came back indicating there was a leak in the sprinkler system - and it included this picture.

House built around 2014. Is there anything special about a residential sprinkler system that makes it different from regular plumbing?

I have sweated plenty of copper joints as a diy’er over the years, but I figured i’d suggest he call in a professional here. But does he need a “sprinkler tech” or something like that?

Does the system need to be drained first? Is extra there liability? Even looking for a “sprinkler expert” is hard because all you get are Lawn Sprinkler companies!!!!

Standpipe

I'm wondering if there is a simple way to add a standpipe for the washing machine drain. I am about to reinstall the laundry sink (1 1/2" drain) and thought this might be a possibility. The present setup has the washing machine draining into the laundry tub.

Any idea what is causing this leak from water tank bolt?

I noticed damp marking tracking from one of the bolts holding the water tank. When i look at the bolt it seems the installer scratched the outer tank surface with the bolt. Also i have not detected any strange behaviour of the boiler it seems to work fine. Thanks

Sump pump running every 3 minutes in Spring

I live in St Joseph County, Indiana (Walkerton/ North Liberty area). Moved into this property (built in 2022) June 2025. From June through February the sump ran normally — only during heavy rain, cycling for a day or two then stopping. No issues.

March 2026 everything changed. We had a flash flood warning, the pump went from cycling every few hours to every 2-3 minutes and has stayed elevated ever since. Now in mid-May it's still cycling every 3 minutes.

What I've already ruled out and addressed:

  • Float is functioning correctly, manually tested
  • Check valve is intact and properly installed
  • No water meter anomaly — city water leak ruled out
  • Discharge pipe is clear — snaked the full corrugated run, no blockage
  • Discharge drains to street storm drain, verified no backflow path toward house
  • Sump pit inlets (French drain) are actively flowing — confirmed groundwater source, not recirculation
  • Installed a battery backup pump as a precaution, and kept a spare pump at hand
  • Basement has stayed completely dry throughout

Anyone is dealing with this?

I've asked my neighbor and one told me he got three pumps running the whole season, and the other neighbor said it's abnormal and should be checked.

What do you all think?

Solution for sediment filter that gets clogged quickly?

We have well water. The picture is where it enters our basement, the ~6 month old pressure tank and a sediment filter. We've lived in the house for two years. During that time, we've realized that if we use a lot of water (running the hose for a while, a series of long showers, etc.) then the pressure in the entire house decreases.

If we flush the sediment filter (I just hold a bucket under it and open up the valve at the bottom for about ~5-8 buckets of water), then the pressure will come back. It seems we're doing this pretty frequently, especially over the summer months when we're using the hoses outside more often. We have no idea how old that filter is.

Is it normal to get reduced pressure and need to flush a filter like this? Should we replace it with a newer, bigger, better one? Is this an indication that our well pump is pulling up too much sediment?

Thanks!

Chair height round flushometer toilet?

I am unable to source a comfort height/chair height flushometer toilet that is round. The bathroom is very small and the door will hit an elongated toilet, but I need the extra height for my mom.

We've been using a temporary lift toilet seat but it's not ideal.

Can anyone point me to a source to buy a chair-height round flushometer toilet? Any rough-in size will do.

shower wall is leaking?

3 days ago fiancé and i noticed a small drip forming along the caulk line in our shower. it quickly turned into a steady trickle, and then appeared from another spot above the caulk.

we immediately shut the well pump off and contacted our landlord. landlord has done nothing and basically said that they didn’t know why it was doing that and taking the shower panel off would be “impossible”.

well pump has been off and the leak stops when there’s no pressure in the system. we turn the water back on to do the dishes and shower quick, and the leak starts back up as soon as the water is back.

obviously we are going to keep bugging our landlord and push them to call a plumber. any insight anyone could offer in the meantime would be great, thanks.

more context if needed:
- corner shower, no idea when it was installed or who installed it
- very high iron content in the water, not sure if that would effect anything

Sunnyvale CA – Sewer backup, hydrojetting done, plumber found offset at property line. Recommending $6000 for excavation and fixing offset with city facing clean out is Camera footage inside. Sanity check needed.

Background:
I had a sewer backup at my home in Sunnyvale, CA. Called the city first — they confirmed the blockage is on my lateral line, not the city main. Hired a licensed plumber who hydrojettted and cleared the line including camera inspection.
What they found:
After jetting, they scoped the line and say there is an offset joint near the property line, located under my driveway (concrete). They’re recommending excavation to fix it.
I’m uploading the camera footage screenshots — would love your read on:

  1. Does this actually look like an offset to you?
  2. Are those white strands root intrusion?
  3. How severe does it look?

The Estimate:
• Saw cut and remove driveway concrete
• Excavate approx 4ft wide x 4ft long x 6ft deep
• Replace pipe section with ABS
• Install property line cleanout
• Backfill, compact, restore concrete (standard finish only — no specialty matching)
• Permits included

Video is backwards, taken while getting the camera out

Can a relative beginner move this?

I know the sink looks bad, I want to replace that and move the whole thing over. it’s currently sitting directly over the sump pit which was a pain when I recently had to work down there. I think I could figure out how to extend the drain but I don’t even understand what the vent piping is for.

can I just cut all that off with a sawzall and connect pvc somehow? I’ve never worked with copper, pvc or pex.

thanks

Does anyone know the name of this handle I broke?

I have this grohe shower handle combo that was installed by previous owner. The volume handle has gotten harder and harder to turn over the last couple of months, and it finally caused the handle to just snap.

I think the cartridge needs to be replaced, but I can’t figure out what model this is and what the replacement handle or cartridge item numbers are. Can anyone help? Thank you so much.

Weird pipe in house

Hey y'all,

Recently there has been a stink in my partner's place and it's been localized in this area. Here are some things for context:

- moved a few months ago, never had this smell before

- today was really hot for the first time in apartment

- around this pipe thing (in the kitchen, beside washroom) smells like sewage or "when you go into a restaurant washroom and the building is really old and has that dank smell"

- small space, making entire apartment stink

- Ontario, Canada area if that narrows down any house architecture related things

It's been driving her insane and I'm also curious as to what this thing is

It’s Leaking…😩

I have a leak that I can’t find. I tried die testing and still can’t find the leak. Water will lower to the bottom of my skimmer and it will stop leaking at that point so naturally I would think that the problem is in the skimmer I have I have put sealant around the whole skimmer and it still leaked. I have tried die, testing the jets coming back into the pool still nothing. Next to my pool is a large set of bushes and then there’s open yard, and this is where the water seems to be going.

Can anyone give me any other suggestions?

Seeking help identifying cartridge model?

Apologies in advance for the general question, like the title says, I'm looking for some help to identify what replacement cartridge I might need for this peerless faucet, I have tried looking online but can't seem to find what model this faucet is to lookup the cartridge number.
