Hi - we have a pump installed in our airing cupboard and a shower in our ensuite that is used heavily by the whole family. It's been running fine for the last 3 years.
Today 3 showers were taken before 7am with the last shower running erratically (water in the cylinder running out).
On our return this evening, the shower pump's not working - changed the fuse and it started again, but only works when the shower is set to boiling hot - ie, no cold water seems to be running through the pump.
Have we broken the pump? Any ideas for a self-fix? Or do we need our plumber?
Thanks so much everyone.
