TRV'S central heating upgrade.

Challenging day fitting 10 TRV's to a central heating system with a mix of 15mm and 10mm pipes.  Always the unexpected catches you out.  Some of the radiators were fitted to pipes that came through brick walls and having no play it was impossible to negotiate the TRV so had to resite the rads just a few mil higher.


Also why the hell do people not fit seperate header tank service valves to CH systems.

Had to isolate water to the house as I am not going to mess with the dodgy looking ball valve in the tank.

Really needs replacing.

Obviously introduced inhibitor into the system and flushed first.





Good job I filled the kettle... ;-)
