hi, just updating bathroom and fitting a thermo bar shower to replace a tap shower feed. Old tap feed also only had tank cold and mains hot so was a nightmare to balance out and not get backfeed and cold shower.
Anyway, hot water from vented cylinder is 22mm, had fitted a new feed from the cw tank in the loft in 15mm. Shower flow is not great (7.5 l/ min) so would it be worth changing cold feed pipe to 22mm?
cw tank is about 3m above shower head, mixer is good for 0.2-5 bar. Planning to get a combi in the longer term which would largely resolve pressure issues but if 22mm is worth it i'll do it now.
thanks in advance!
