Got above where when heating switches off boiler is getting a feed from somewhere, causing clicking noise as it tries to go through start sequence. Where would it get it from, through cylinder Stat or 3 port.
Going there tomorrow to check it out but wanted to grab a replacement just in case.
Looks like someone has had a water softener connected via the washing machine connections either side of balofix valve. Replace that hose with softener connections and close balofix bypass.
You need to give them the opportunity to repair their error, if you do get another company in to deal with it inform them you will have to do that and photograph everything with time and date stamps.
I would copy the HSE on any communications and clearly show that you have to the HA.
You may also ask that the system is not used until it it is confirmed it is safe. When was the last time someone accessed your property to check the tank.
