I’m trying to figure out what this thing is called on the outside of my house. It’s a hole that’s located on the exterior wall directly below the upstairs master bathroom. It’s about 2-3 inches in diameter with a wing nut in the middle. My plumber has used it before to snake it when trying to clear a big problem with our drain. I’m just curious what this thing is called. The cover has rusted and no longer tightens, so when we flush a toilet, water rushes out. I want to see if I can replace the cover myself and avoid the plumber’s fee.

Our home is heated by solid fuel (coal) heating that gets circulated to each room via radiators. My neighbor chapped our door last night to say that it looked like our house was on fire. There was steam coming from the roof. It turned out that it was from hot water that was exiting an overflow pipe. To be honest, I did not even know the pipe was there before now. The house is old and we’ve only been in it for a few years.
I’m an American now living in the UK and sadly, I don’t know much about these types of heating systems. We have a heating unit/tank that heats the hot water for our home as well in addition to this back boiler thingy.
The pipes have been much louder this winter when we fired up the fireplace and we were told there was probably air trapped in the radiators. I’ve bled the ones that I can get open and found there was no air in any of them, but do have three that won’t seem to open.
My questions are:
1. Is it possible that there is air in these that I can’t open and it’s causing the problem?
2. If it is, how do I bleed the radiator if the key does not make it budge?
3. What’s causing the water to need the overflow pipe?
To any Americans that wish to pass comment on using coal, please spare me. It’s anthracite coal and clean burning. The village I live in does not have gas and I don’t use an air conditioner six months of the year so zip it.

we ran out of oil. our water is heated by oil. if i heat the water from outside,like with a small propane gas grill or propane torch where in the plumbing should i try heating it. i need to do dishes and shower. im thinking the tank

I was told that it’s illegal to ‘re-install’ a hot water heater inside a house and that it must be relocated to an outside closet or garage. Is this true?

A plumber installed shut-off but now it is buried under the ground. Are there plumbing requirements?

1930’s home just bought last year. House was completely refinished with new electrical and plumbing. Basement was all new construction. Leak appears to be coming from toilet. Tiles leading out of bathroom are stained and rug right outside bathroom has water spot not coming from anywhere so it must be piping. A few question…how best to fix and how much will it cost? Also who is responsible for damage since we bought 11 just months ago?

Is my water heater going bad?
