hopefully someone can help me.
im fitting new plumbing including a 218ltr vented cylinder.
1. i have seen gate valves used on the cold feed before, i also no there is no valve aloud on the vent pipe. Do gate valves restict the flow? i was going to use full bore lever valves if they do.
also i need to buy an 27" element. i have seen 2 types, the standard one, then theres this incalloy type, its only £4 more is it worth the extra i live in a hard water area. thanks in advance.
