Installing a new shower

What about it?

I'm installing a new shower in my basement and I want to make sure I'm not making any mistakes. I bought green mold resistant gypsum and I was ready to glue my vinyl walls of my maax shower on them. What would be my next step if I want to do it right? Paint a waterproof membrane on my gypsum? I just want to do what's best!

AAV placement

What about it?

The AAV is in the top right of this picture. From what I can find on Google, should it be directly above the drain pipe, after the p-trap? I’ve got a clog and wondering if this has something to do with it.

Shower floor

What about it?

So I was thinking I'd like to use these pebbles for the floor of my shower, but I fear the upkeep would be a major obstacle. What would I have to do to keep this from building mold and bacteria? How often would I have to take them out to fully clean & dry them? If there is a better sub for this question I'll be glad to be redirected!

How to remove old tub drain

What about it?

(Apologies for the gross close up) This i believe is an American Standard tub drain. Its only got 2 nubs, so I'm kinda baffled on how to remove. I'd like to replace it and the overflow plate. Probably original to the house so 50ish years old. Any advice on the tool for the job would be great!! Thank you!

How hard/expensive would it be to have an old well tank/pump removed?

What about it?

This is the old well pump/tank in my basement connected to my houses original (1945) hand dug well. A drilled well was out in in the 80s and this was left here still connected to the old well and houses plumbing (shut off at that red valve to stop it from filling). I was looking to go solar and remove all of this old equipment to put a battery backup, it's the only wall space I really have in my basement. How big of a job would this be for a plumber, is it as simple as ripping all this stuff out and plugging the pipe to the old well?

Does this pass Reddit inspection?

What tool do I need to use to take out this tap?

What tool do I need to use to take out this tap? I'm in the UK if that means anything

Am I screwed?

What about it?

Greetings all, I'm not 100%sure if this is the correct sub for this... BUT... due to recent flooding in my area my blower for my boiler got a bit wet, as you can see from the photo it is about halfway up the motor itself and the air band is pretty well submerged. I knew I was going to be out of town for a few weeks so I had shut down the boiler about 2 weeks prior, no power to the unit and the burn box was cold when it got wet. Is there hope of saving the blower assembly or am I in for a world of hurt when it comes to calling in a plumber?

Why does this happen to my basement bathroom sink?

What about it?

I have to clean this (what looks like remnants from dirty water) from my basement sink every few weeks. It and the rest of the bathroom rarely get used if that adds any context. I haven’t done any work to this bathroom since we moved in 18months ago.

I need to replace the face plate that goes here, but I’m not too sure which one I need to get. Any suggestions?
