Hi guys, bear with me, as I am but a humble carpenter. I have just installed mixer taps on my bath using flexi connections, the pressure now is less than that of the sink. Any ideas as to what would cause this.
Well, high pressure taps on low pressure pipework, i.e. tank fed, skinny/kinked/squashed flexi`s, pipe blockage, probably the first one, this is why you pay your money to decent plumbers and not DIY
By "skinny" anta, do you mean a smaller inside diameter on the flexis. The pressure on the nearby sink is quite strong, on 15mm pipe, fed from the same tank.
There will be more resistance on the basin taps compared to the bath mixer,making the flow rate higher.
Apparently the flow rate was fine before the new taps/connectors went in. I was just wondering if the pushfit connectors had something to do with it.
If you do the following the flow rate will increase:- Replace isolators with "full bore" 22mm isolators. Throw the flexis away (reduce flow rate substantially). Fit 22mm all the way to the tap connector (copper - or if you have to - plastic). Hope this helps.
Won't make any difference if the taps need a bar of pressure though. Check the book that came with the taps for every 0.1 bar the taps require you need a meter of height to the tank. So if the taps require 0.5 bar minimum to work at optimum level your tank needs to be 5 meters higher than the tap! Got it?
