Well I'd like to have enough water coming out of a tap to clean my teeth while someone is running a bath! There are bathrooms on the top 2 floors (one on each, shower only in the top one) and I would like for guests to be able to use one without having to explain that they can't if I am using...

Wel, I cleaned the strainer on the 1st PRV - nothing there. More of a slight yellow discolouration than anything, no debris- came off with a rub of the thumb. The housing on that PRV says 3bar, but it is an adjustable type with the 5bar sticker over the adjustment screw; so I assume the...

'standard' gravity fed shower. (I assume that is the term) with thermostatic mixer. Part of the reason for installing the unvented system was to negate the need for pumps. It backs onto the cupboard the system is in so prob about a metre of pipe! Flow in there is no more than adequate, well...

Actually, regarding the PRV in series question - it is redundant in my case as the 1st is 5bar (awkward to get to it but finally got to see the label) and the 2nd is 3.5bar; so in my case (assuming they are working) is is a natural step-down anyway. The strainer in the combination valve PRV...

Regarding the flow rates - almost. The garden tap (where mains enters the property) is indeed 22l/min. The 17.25L/min reading was for the bathroom only - A reading for the bath alone was 17.25 and for the bath and bathroom sink was also 17.25ish (the basin was 4L/min and the bath 13.25L/min...

The softener is rated to 55L/min and I asked them to use the hi-flo installation (essentially using 22mm rather than 15mm hoses), but I have also tried bypassing it with no change. The main kitchen tap is softened (not having washer/dishwasher softened missed half the point of installing it)...

Tried it from the bath only, and then the bath and the trickle that comes out of the sink if you run both at the same time and both come out at around 17.25L/min. I would say this is pretty poor for an unvented system, but you can't get out more than you put in, so the inlet is the prob (but...

Obvious now you say it! Another flow issue searches came up with was to check that all stopcocks (including external) are fully open. Which I have done (in fact got the council to replace my external one which was actually buried - I thought that would do it, but no and that is now a plastic...

Apologies for bringing up unvented systems - but I have searched and can't find an answer to my question. My problem - in a nutshell the flow rate at showers etc isn't as good as I would have hoped. My plumber (in retrospect I shouldn't have paid all the cash) blamed the flow on the mains...

And just to add - Now I have replaced the expansion tank - it seems to hold pressure fine (the coupling wasn't that tight when I removed it; but I don't see how that would affect the pressure in the 'air' side of the membrane. And it's not as though it was leaking so that may well be a bit...

http://www.santon.co.uk/306.htm Moved to unvented domestic water system - to do away with cold water storage tanks and provide mains pressure hot water so no need for shower pumps. Plumber who installed turned out not to have a great deal of experience with unvented systems, but was under...

Hi - new here and after some help! Had poor water pressure for showers etc so upgraded the house to a sealed system. Problem is that the pressure is fine for about 10-20secs in the shower bath etc then drops right back. After switching off for a while the same thing happens again if you...
