Please help, novice(ish) diyer.
Saurday is changed bathroom bath and shower taps.
Could figure out how to shut off hot water (I missed the big pipe at back of airing cupboard - my wife loves to cram with towels bedding etc). But turned all the values I could find off.
So just drained the whole system (mains turned off and ran hot taps until water stopped.
Once finished turned mains and all other valves on, hot taps all work fine, but showers (we have 2 running off same shower pump) have no hot water (worked fine although pump v noisy before)?
Need some advice, pump is showermate, it has 4 pipes into it, 2 with red connectors 2 black, the red (I assume hot water) pipes one is hot and the other isn't - wondering if there is some air, and if so how I release.
Appreciate any advice - Thanks
