Some time ago I fitted ball valves in line to poor performing gate valves, feeding the bathroom from a cold water tank in the loft and hot water storage cylinder. I emptied the cold water tank in the loft.
The ball valve to the cold water feed bathroom taps went in fine.
However for the cold water feed to the shower, I was not able to stop a flow of water out of the shower head. Obviously I didn't fancy cutting in to the pipe so I remember partially dismantling the gate valve and water came gushing out. The gate valve is about 30cm (12inches) higher than the mixer for the shower and runs vertically directly down from the tank in the loft.
I wondered if there was an amount of water in the cold water shower loop that is always "stuck" there. Is it a simple case of having a bucket and towels handy and then dismantling the gate valve prior to cutting and fitting the ball valve?
I plan to replace the shower unit soon so wanted to get that ball valve in second time round!
Any advice appreciated.
