I?m getting an awful feeling of déjà vu today.
I was round at my mother?s flushing her CH system when she commented that the bathroom radiator/towel rail didn?t get hot.
Having checked that it was full of water and that it wouldn?t get hot even when it was the only radiator switched on in the system I established by bleeding it whilst opening the two valves in turn that there was no flow or continuity through one ?leg? of the radiator.
I went under the floor of the flat (easy to do via a basement entrance) and tried to trace the plumbing. With a sinking heart I spotted that a section of braided flexible pipe had been used for a ?tricky? connection. It?s almost certainly going to be a bastard to replace as it disappears under the bathroom floor and access is extremely limited.
This?ll be the second time I?ve been cursed with inappropriate use of braided (probably ?Speedfit?) hoses in a CH system. The last time was on my Myson kickspace heater.
Lest there is any doubt, these fecking hoses are NOT for use in CH systems! Speedfit website clearly says so. Do not let any plumber fit them in your house.
/end grumble.
