Repairing severely damaged floor joists in constrained spaces

“I need help with a stuck OBD port, any advice? I recently tuned my car's stage 1 with the FlashZilla Pro OBD port. However, I'm in need to remove it so I can check my car's error codes and whatnot. Unfortunately, it's stuck. I mean, it won't come off no matter how much I pry with a non-marrying stuff tool, or wiggling it left to right. I'm frustrated and have tried contacting Tunezillas' customer service, but to no avail. I also cannot take off my bottom panel from my car. If anyone has any sugg”

“Will a 2" vent support three bathrooms? I'm renovating a 2nd floor bathroom in my 1908 house, which is currently the only bathroom tied to that stack. I'm planning to add a powder room directly below this one and possibly a bathroom with shower in the 3rd floor attic, so I'm trying to make sure everything is plumbed and vented appropriately to allow for this future work. Here is the piping plan I've come up with. The bath vent will join 2" vent stack in the attic, which will then tie to the main”

“Replacing floor joist without cutting into hallway Part of my subfloor was rotting out near the toilet on the second floor. The rest of the subfloor was in pretty bad shape from a previous owner’s renovations attempt to remove some sort of laminate. I decided to go ahead and just replace the entire subfloor of my second floor bathroom. Unfortunately, when I removed the subfloor, I had the full view of what was done to some of the floor joists. I am planning on fixing 3/4 of the floor joists with”

“Do the notches and holes in my floor joists warrant urgent repair or replacement? When plumbers came the plastic pipe under the joist was completely blocked. I got them to switch to copper, to do that they had to notch out of the wood. Annoyingly they did it right where the old holes were. Not only are the notches quite big, but also its above the existing holes. I’m a bit worried about the structural element, and especially since the floor has been relaid at a cost of £1k I’m a bit hesitant to ”

“Do my floor joists need to be upgraded for a bathtub install? I’m hoping for a quick sanity check on some structural advice regarding a bathroom renovation. We are renovating a bathroom and adding a new bathtub. Span: 2.35 meters Existing Joists: 5x2 (120mm x 50mm) One end of the joists is notched into the web of a 4-inch (approx. 100mm) tall steel beam The problem is, the Structural Engineer has calculated that the existing 5x2s are inadequate for the new load. Suggested adding new 6x2 joists a”

“How to remove a mirror stuck to a door with sticky pads? I have a door with a large mirror stuck to it with what appears to be ~2mm thick double-sided soft sticky pads. I'm replacing the door handles and latch. The problem is that the replacement door-handles have a larger plate (chosen so that the plate will cover up the marks from the old handles), and this mirror will interfere with the new door-handle's plate: Obviously, I need to remove the mirror to get the new door handles on, but I would”

“Removing a jet-tub's pump? We have a builder's grade jetted tub in our bathroom, and the pump has gone out. It just buzzes.[*] Thankfully, the plumbing fittings are threaded, the pipes that connect are possibly flexible enough for egress/ingress, and I was able to source an OEM replacement pump. However, whoever installed this decided to anchor the pump down with screws on the least-accessible feet, completely ignoring the 2 easily accessible feet. I can feel the screws, but cannot see them.
