Protruding water lines blocking shower installation

“How to replace these 2" swimming pool PVC valves? I need to replace some old 2 inch PVC ball valves on my pool pump's suction-side manifold, but I am running into clearance issues due to how tightly the original fittings were glued. Here are the solutions I’ve considered and why they won't work in my opinion: Option 1: Replace valves directly with union valves. The problem: There is only 15mm of exposed pipe below the tees/elbows. To my understanding a pressure-rated PVC union valve requires at ”

“Slab-on-grade framing: How do I properly protect the wall from water/pests, etc? I'm renovating a house that was built in the early 1990s. It was built on a single monolithic slab, including the attached garage/laundry. In the attached garage (with laundry, water heater, and well pressure tank co-located therein), there is a lot of rodent and water/mold damage at the base of the wall (both inside and out) that I'm trying to prevent from happening in the future after we repair it. I've only ever ”

“How to deal with this copper pipe protruding into alcove shower space I have ripped out the incredibly disgusting, broken, 30year old acrylic alcove shower that came with my fixer-upper in preparation for replacing it with a tiled one. The alcove is very small (~36x36). I have discovered that the builders exploited the geometry of the old acrylic shower (it narrowed at the base) to do this - these water lines protrude about 2inches from the floor plate. However, they are T'd into another line th”

“How to fish ethernet through ~1 ft run, instead of stapled coax? I thought this was going to be an easy fish.. seamlessly attach the ethernet to the coax by lopping off the terminations and taping them together head-to-head with some masking tape. However, it seems the coax is stapled inside this small run inside the wall... meaning i cant do that without opening up the wall (which I dont want to do, unless necessary). They used massively overkill (inch-long) staples for the one I already remove”

“Are these plastic gutter screens properly installed? The bottom of my roof, around the front door, stays damp for a long time. I think this is because the roof screens where not installed properly. Although somewhat practical, I think it's worse to have such if the bottom of the roof is going to rot pretty quickly. First I drew a figure to try to show all the elements. I think that whoever installed the plastic screen did a poor job. First of all, one of the gutters was lose and it looks like th”

“Penetration through complicated wall My home has a very annoying little room I am trying to use as a network closet. The annoying little room is a small closet under the stairs. I can access this small closet by using a short (maybe 40 inch tall) door in the garage. Local code seems to demand the whole garage wall should be a two hour fire rated assembly, and all the interior walls in the closet should have 5/8 gypsum, etc. I would like to make a penetration from my closet into the garage. In or”

“Why is it OK for countertop dishwasher vent to have smaller tubing than dishwasher waste tubing? I thought that a "golden rule" of plumbing was that drains always get bigger as they go on. Whether its gutters or toilets or sewers, you never drain a bigger drain into a smaller one--right?? So I am confused by why my Bosch dishwasher has a roughly 3/4 ID drain tubing (standard Bosch drain tubing) but my industry standard, California code required air-gap has noticeably smaller - 5/8 OD, even small”
