I was planning on changing the seized gate valve in my airing cupboard supplying cold feed to cylinder from cold water tank in loft.
The pipe is old imperial 3/4" and the gate valve is also 3/4. I bought a 22mm Pegler compression valve and 3/4 brass olives for the job. Tonight though I'm thinking if the existing olives are knackered and need to come off (I have a puller) and leave the an indentation on the pipe the new olives might not make a good seal.
So, my question is, am I better off just cutting the old pipe near the ceiling and as low as I can go and using a 22 x 3/4 end feed couplers renew the length with 22mm tubing instead? I don't mind soldering if this is the best option. I'll leave the rest of the pipework from the tank etc so I'll still have some old 3/4 in the loft.
Any advice appreciated
