Whats the dynamic pressure. 2 bar is poor standing pressure imho.
step 1, disconnect mains and connect new mains to outside, do dynamic pressures and flow rate with open outlet
step 2, reconnect mains with new pipe from meter (if accessible) to house
step 3, do dynamic pressures on mains with system connected
step 4, check every single outlet (that is accessible) for dynamic pressure, flow before and after taps.
Hi Mate
just been reading through the threads some good advise there
however with a large house and with such a big loss in pressure i would start by
confirming that you have good water pressure at the meter on both sides, if so
1) take pressure reading before stopcock
2)take pressure reading after stopcock ( are there the same ? )
3) check all out lets on ground floor only, and check standing pressures ( is their a difference ? )
4) move on to next floor and repeat stages 1 -3 and so on
keep in mind all taps are closed and you are checking pipe work and standing pressure
my idea been is you will be able to check for lost pressure, once you have found lost pressure you will be able to isolate that area put a temp line in and then check standing pressures again
if you are happy with standing pressure move on to checking working pressures
this time remove excising tap and put a temporary tap in its place and check water flow do this one at a time and check flow rare
I know this is time consuming put it will be a question of eliminating blocked or restricted pipe work and will give you some idea of where the problem is
hope this helps
thanks Tony
