Is it ok to have my outdoor washer drain into the sewer hole?

I’m clueless, would appreciate any help.

Plumber left tool. What is it?

Hired a plumber and they left this tool. It’s been days and he hasn’t come back for it yet. What is it?

Sigh

I work for a large contractor. We got called out to finish a job that was started by another (normally) reputable company. This is for an apartment complex. The maintenance manager started noticing stuff like this. The main line into the building was leaking under the slab, and he was under the impression they were going to fix that in the bid. Not only did they not have any intention of solving their biggest problem, they littered the walls with these kinds of goodies. Random sharkbites to old cpvc where they claimed it would be too hard to repipe it. They even used sharkbite couplings to connect the brand new pex upon occasion. I can definitely see why they got the boot. Thanks for the business, I guess.

What plungers are you pros using?

I do maintenance and I'm really sick of flimsy plungers that don't reform or just suck in general. Any brand/model recommendations? I'm forced to order through Fastenal sometimes Granger and their selection is garbage.

Will the copper touching the galvanized unistrut cause a problem in a dry basement? Mounting a tankless and I want to make it look perty.

Shower handle not working correctly?

I turned the faucet on and noticed the faucet felt loose. Then the faucet isnt turning how its supposed to. I try turning the faucet off but water was still running. If I try to turn the faucet all the way to the right how its supposed to, water runs but if I keep it in this position of how I turn I have in the picture, the water turns off. How do I fix this?

How to open/separate those two pipe?

Stupid question maybe, but how should we open or separate those two pipes? I’m not into plumbing so I don’t know either how or which tools to use.

How to make this proper with p-trap and sink strainer?

So I got a new basket, plumbers putty and pvc glue…need advice on PVC pipe fittings. Water leaks from the hose to the dishwasher and also under the basket. Never did any plumbing before but handy with tools. All advice appreciated…thanks !

How bad is this? Looks janky AF

My building has been “upgrading” its plumbing, since the work in the pic was done the water pressure in my shower has been severely reduced. The maintenance crew is going to attempt to fix it tomorrow, but seeing this I’m sort of doubting their ability to do so lol

Tank lid ID?

The tank lid on my friend's toilet has been broken for a long time and I'd like to buy him a replacement for his birthday. I only have this one photo that he sent me and no idea the brand name (id ask but i wanna make it a surprise) Any help would be appreciated.

Is this setup correct ?

Hi everyone, I just bought a house with a pool and I’m trying to get the heating system to work. After a bit of troubleshooting there is hot water coming to/from the heat exhanger so I reckon that’s ok for that part but the temperature of the water in the pool won’t rise the slightest even after a whole day. My next guess would be an improper setup of the bypass valves but if I’m not wrong on how those valves work it should be in a « 100% of the water goes through the heat exchanger » mode. And yes the pump is running, kinda hard to tell what path the water is taking by feeling the pipes because the pressure is not that high and the whole thing is rumbling due to the filtering and heating systems running.. Thanks !
