How can this be going on to 8 pages
Makes you wonder when we said what the problem was on page 1
Good for the old post count

Ok, blame the europeans but it don't answer my question.
If its a mixer tap designed for equal pressures then the only time the higher pressure may backfeed to the loft storage cistern is when both taps are open .

A blockage where ?

You stated " It took around 1 hour to run and fill a bath so the cold water feed was tapped into the mains instead and the cold gravity "
Only a guess going by what you wrote.
As this pipe is now obviously de-commissioned then it is of no relevance anyway.
As I said my gravity cold supply to my bath will fill it in a few minutes.
If it took an hour I would suspect a blockage.
Dead bird or something stuck in the end of the tank connector mebbe.

Considering the water level in the cistern had been reduced in the morning time , then turning off the bath mixer tap isolating valve a few hours later is no indication that the level did not rise in the cistern due to a problem else where.
I assume no one turned on any hot taps during this test period and you periodically checked the cistern to be certain that the level was being maintained ??.

The cold water mains feed to the whole bathroom was turned off for about 5 hours yesterday.
During that time , the toilet was flushed once and a couple of taps where ran briefly.
This took the water level in the storage tank well below the overflow pipe and I checked periodically that the water level in the storage tank didnt rise and it never.
As I have fitted a NRV to the kitchen mixer tap and the bathroom basin mixer tap , it must either be the electric shower or the bath mixer tap.
After listening to all you guys , I suspect , as earlier diagnosed that the problem is in having no current NRV fitted to the bathtub mixer tap.
Correct ???
That's an assumption, not a deduction. A faulty NRV would cause no end of confusion. The only way to be certain is to fit an isolating valve on the supply to the faulty tap, shut the valve, open the tap, and observe that the level doesn't rise. You might need to ban the family from the house while you do this.ScottJH said:
Incorrect.
The problem is a faulty tap on unbalanced supplies.
The remedy is to balance the supplies.
The workaround is to fit an NRV and cross your fingers.
