Turning counter with high rise breakfast bar into just an island, I'm no plumber and I believe what I see is the loop vent for the plumbing to my sink. It is a tad to high so I was curious if I could just simply trim these 2 lines down to make the height go right under a new countertop. As I stated I'm no plumber haha just trying to get advice before destroying something. Thank you in advance!
Is there a good way to unglue those fittings? I would hate to not be able to reuse them, cause I simply can't seem to find those specific angled pieces online at all
No. You need to access both pieces of vertical pipe from the opposite side of the wall and cut out a section of that vertical pipe on each side of the loop vent. (You will reuse everything above the cuts you make) However much you need to lower it is roughly what you need to cut out. You need to be able to rejoin that top section of loop vent to your cut pipe with two pvc couplings, purple primer and pvc glue.
You cut the pipe, not the fittings. And since you need to use a coupling, you need to leave at least 1 1/2" of pipe above or below a fitting like a 45 elbow in order to have some pipe to glue to.
In other words, don't cut the loop vent off right at the bottom of an elbow. Cut it at least 1 1/2" below the elbow to leave some pipe sticking out. More is better, in case it needs to be redone in the future.
Totally makes sense now. Will I need to turn off the water for doing this, I would think not cause it's simply air in there correct? Just covering my bases and thank you so much for the help l, truly appreciated. Doing my first big home DIY so trying not to screw it up.
Just an update, started work again 9n it this morning, got the pipes exposed from the backside. Just a question, been working with a saw saw, can I use that to cut the pipes or would that be a bad idea?
In a spot like that with wires and sheet rock close by, I sometimes use one of those cheap wire saws (in the camping dept.) Just takes longer than a power saw. Draw a line around the pipe with a marker so you can keep the cut "square".
A sawzall will work just fine, you just need to be careful and make a very straight cut. Having someone help by holding on to the pipe for you while you cut would be a good idea.
I'm tackling a drainpipe leak in my crawl space and could use some guidance please!
Attached are pictures of the area from several angles. The leak is in the 1.5" just below the copper Y.
I don't know if it's just a failed solder, or copper that needs replacing. Everything in this house seems to have been done poorly originally (1978 build), so I'm inclined to assume both.
The copper above the Y goes through a concrete block wall, so I don't really have more than a 1/2" wiggle room at best to fit pipes together. Honestly since the Y is connected to a toilet directly above, there may be absolutely no wiggle room.
I'm assuming I need to replace everything from the threaded copper going into the cast iron up to the bottom side of the Y. But with so little wiggle room - how??
Thank you! Looking forward to the commentary on the work. Not my handiwork, so you won't hurt my feelings! ;-)

I took out a one piece shower and tub surround from the 80s and in it's place I'm going to install a surround standing shower, no tub. The drain for the shower is in the middle of the floor so I need to get it to where the old tub drain was. The trap needs to go under the drain, I assume, and then I need to get the pipe to where the old tub drain was. I'm going to cut the old P-trap off the pipe and run the pipe to where the p trap is. My question is, does the pipe from the shower drain need to be at a pitch towards the old location or can it be straight. I don't think it will be pitched once it's installed and I'm not sure if that's a requirement
