This is a very common problem that keeps cropping up on Skill Builder.
Here is Joe’s message:
Roger! Your advice saved our new build home and has probably avoided thousands £££ worth of damage.
Moved into a new build home 4 weeks ago and with the onset of colder weather, we began to use the heating.
Realizing that some of the radiators were cold to touch, they needed air bleeding, which I then re-pressured the system via the filling loop valve.
However, over the past week or so, it keep losing pressure. I re-pressured and the following day it would be zero bar again. It culminated with a leak tonight.
After watching your video and following your advice, I re-pressured, and checked the radiators and an en-suite radiator was leaking. Called out an emergency plumber.
They quickly diagnosed that the tradesperson who installed it drilled a screw through the pipe when installing the plastic plate/cover.
LEAKING inside the cavity wall over the past few weeks until the screw had given up, and then it leaked. If I hadn’t of watched your video for advice (as advice from a new build developer is non-existent), this could have gone unnoticed for weeks/months.
Thank you very much! I’ve been following your channel for a while now, and I continue to watch your videos! I’ve attached photos of what happened.
Thanks so much! if I hadn’t watched your video, it would have never led me to find this leak and poor workmanship!
