I have an external cavity wall which has a line of bricks which jut out (about half a brick) to form a cosmetic detail line just under the first floor window level. I understand that this would now make the house difficult to mortgage due to a risk of cracking, should these bricks break down...
By the way, the 2 stage TCOs have two temperature settings - e.g. 57C and 90C as a previous poster says.
At the lower temperature, it switches off the supply but will reset when the water is cooler again (Prevents scalding but causes hot/cold cycling in some cases).
At the higher temperature...
Good point Nickso - I'll get my inlaws to check the BG contract level they are on, but I suspect it's not the one that covers the supply pipe... or the BG engineer would have happily sorted it ... wouldn't he?...
My inlaws say the engineer did check the pressure at the meter and it was "ok" - so I assume that there is a pressure drop between the meter and the BBU (approx 8 meters), as you'd expect.
Anyway, your advise seems be be that they should get a second test/opinion from a private engineer, so...
Thanks for the feedback but I still don't understand if it's dangerous or will the boiler just run less efficiently?
Should my inlaws live with it as-is; get a re-test; or upgrade the supply (which has been OK for some 20ish years)?
It's worrying for them at their age but I don't want them to...
My aged inlaws (80+ years) recently had a regular British Gas service, Despite having the same back-boiler/fire serviced with no problems for many years, the engineer issued a "Do not use" label and threatened to cut off the gas - he eventually left it on "as a favour". He said he could only...
