Water leaking from cold valve when opening hot valve

Water is leaking from the cold valve when either the hot water is turned on only or when cold water is turned on. Which valve(s) do I need to replace? TIA

Does anyone know how this comes out and what brand and size it is?

Not a plumber but I can get by. Took me a while and about 3 different tools before I was able to get the retaining ring off. The brass cover says Eljer but I’m not entirely certain that is the brand. Local lowes does not have the cartridge and I want to make sure I get the correct one before I take this one out and or destroy this one in the process. I found one that looks similar but has two tubes that come in from the side of the cartridge. Any tips?

Sewer smell coming from slop sink

This is my current set up. Washer drains into slop sink, slop sink is draining into ejector pit. My slop sink lately has been giving off serious ejector pit stink. We’ve been here for 4 years and this hasn’t been an issue until now. I understand it probably has something to do with the p-trap losing it’s prime but I’m trying to figure out why it’s an issue now. It never goes dry because we’re doing laundry once every few days. Any advice on how to eliminate the smell?

Any Issues If I leave this always on?

So for whatever reason at my house the spigot is on the wrong side of the fence, so I cut a hole in the fence and attached a sillcock to it so I can have a way to access water with a way to turn it on and off on the other side of the fence where I need it. The only reason I am asking this question is because the sillcock I bought specifically said on it to not leave it on for more than 12 hours / continously. I don't intend to leave that on continuously because I will only turn it on when I need it. But that led me to wonder if the same applies for the spigot shown here. I will of course need to leave that on otherwise there will be no water to the other side of the fence. So that is why I am wondering if this will potientally cause any issues if I leave it on. And yes, I will turn it off when the temperature gets too cold of course. I am just referring to the spring/summer time leaving it on when the temperature is appropriate.

Drain assembly seems too simple - am I missing something?

I had to get my shower pan replaced and noticed the drain assembly is no more than the PVC pipe (fed through the pan hole), a rubber gasket, and a strainer. Is that normal or should there be more to it? Contractor comes back next week to finish, so want to be prepared to finish this right.

Want to put new kitchen. Quick plumbing question! Thanks in advance

Hi all, I want to put in a new kitchen. Is there any way possible to have the sink moved about 15 inches to the left or right or that’s not doable? Thanks in advance

Is there a butt connector that would work for this washer fluid line on my car? It's old and brittle plastic so it cracks easily. The original end is cracked. I tried heating it up to melt it over but that didn't work well

Part identification please?

Delta faucet leak

My Delta kitchen faucet is leaking, I’m 99% sure it just needs a rubber washer but I can’t figure out how to get to it. Any ideas or suggestions?
