I have a bungalow with vented hot water system. I have just had a new kitchen and wet-room installed and performance at modern taps was appalling so have fitted a monsoon twin impeller pump to provide whole house boosted water.
This works fine and has drastically improved flow at taps etc. However when flushing the toilet in the main bathroom although the cistern has filled and ball valve shuts off the pump still keeps running. I have proved this by open and closing a cold tap while the pump is still running and then the pump stops. I think its because the valve closes slowly as the cistern fills so the pump doesn't sense the flow stopping. Unfortunately I cannot get a separate cold water feed to the WC. I have spoken to Stuart Turner tech support and they cant really offer any solution other than possibly changing the float valve. Whats strange is the new WC in the wet-room which is on a Gerberit frame works fine and the previous 1.5bar pump never displayed these problems only the new 3.0 Bar pump. I think the valve in the cistern is a Torbeck with low pressure insert? Can anyone recommend a replacement valve that might shut quicker than the current type or any other suggestions.
