yes toilet cistern fills when tap turned on, a friend of the missus has asked me wht it could be and im stumped lol.

There should be no reason as to why it is filling the system up when the basin taps are on, I would suggest a new inlet valve to the wc cistern 😱

This is impossible to me???

There is no direct connection between the two?

sounds like the valves you have in pub toilets that let the cistern fill when the cold water pressure drops (hot or cold tap turned on to wash hands) . For some reason i can't remember the name of it

i think its called a Cistermiser

Good shout

I took the assumption this was in a home

It cant be anything else can it? Perhaps they've renovated an old pub.....lol

 

[Plumbstar Tom]

you never know,

The new ones have timers now or IR sensors now

I hope it is this as it can't be anything else

I really racked my brain before your suggestion
