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”

“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”

“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”
