Whoop whoop hip hip hooray!!! 😃 So I can finally put all my pans, squash and gin back in the cupboard under the sink now?! Thanks so much for bearing with me. Ok looks like a mole and an unvented is the way forward. Many many thanks for all the advice you have all given...

I put gauge onto DW inlet. With both garden and and kitchen tap shut it read 4.5bar With both garden and and kitchen tap fully open, gauge dropped to 0. So, wishing to attain a pressure of 1.0 bar, I had to close both garden and and kitchen taps very gradually until the gauge read 1.0...

So I'll put the gauge on the DW. Then open kitchen tap and garden tap and measure flow from each. but how do I " leave a pressure of 1.0 bar at the gauge at the DW"? 1) open and close the DW tap to adjust level on gauge? or 2) open and close kitchen tap to adjust level on gauge at...

Hiya, (my previous post only mentions dishwasher, garden tap and kitchen tap, not WMC) washing machine is NOT on mains, dishwasher IS on mains. so shouldn't I ignore the WMC completely now when I measure?

We took off garden tap and measured directly to the wall. Static 3.8bar, 14 litres / min flow +kitchen tap on, dropped to 2.5bar, 12 L/min + dishwasher outlet on, dropped to 0 bar 9 L/min Is this the data required?

You are fast! I'll explain chart: The second line shows with dishwasher outlet open and kitchen tap open, the garden tap had a flow of 6.4 litres per min and a pressure of 0.8bar. 3rd line shows with dishwasher outlet shut and kitchen tap shut, the garden tap had a flow of 14litres per...

Good evening all At the risk of sending myself mad, after a couple of days I have had another crack it this. Bought some more pliers today, and had a go at the seized up stopcock under the sink and with a LOT of WD40 and wrenching, managed to get it moving but found it had been open all...

Many thanks for all your replies. Agile I haven't even heard of a listening stick (I actually thought you were pulling my leg) http://www.hydrohire.com/acatalog/leak-detection.html - £80 to hire ouch Gasguru or a stopcock key or pump pliers (had a go with normal pliers to no avail). I...

mystery jammed tap under the sink, on right hand side. stopcock is on other side of the kitchen. [/img]

Okey Dokey Bath tap from the loft cistern. SO ignoring that too, we have washing machine and dishwasher inlets, kitchen tap and garden tap on mains pressure. With kitchen tap, garden tap and dishwasher open, the dishwasher give 10lpm With other 3 open, the washing machine gives 6lpm...

Upstairs and downstairs basin are low pressure, so I assume from the loft tank, so I'll ignore them. So I need flow rate at each of Kitchen Tap washing machine dishwaher garden tap whilst all of these are open ? ps (are you trying to flood my house?!!) :)

Flow rate - I measured in a calibrated bucket timed for 1 minute.

Morning all OK we have new pressure measurements, which seem to be more normal. Under the kitchen sink, with pressure gauge attached to the outlet for dishwasher, I got That outlet alone: 4.4bar (is this the static pressure?) With kitchen cold tap open as well: drops to 3.2bar...

Agile, ha ha static flow. Clearly too early in the morning for me not to be and make an oxymoron. :oops: Moving swiftly on... thanks for the guidance on cylinder size. I will try the dishwasher connection to measure the static pressure.

Morning all Beautiful morning here. Agile - many thanks. Yes I can see the static and dynamic pressures are crucial, but how would I measure the static flow,other than what I did already? ie measuring at garden tap and showing results above, & attempting at washing machine and...

Thanks Dan. I tried at the washing machine... disconnected it, dragged it out, nearly expired at the rubbish and toys and missing socks hiding behind. but there was some kind of valve on the water outlet. When I attached the pressure gauge and opened the tap, the gauge measured 0. So I...

Thank you Gasguru and Dan. Yes I thought it was odd that pressure increased at garden tap when I opened the kitched tap too. I have just been out with a torch and re-measured! 1. Time 21:01:26 All taps in house off. I attached gauge to garden tap, and reading goes from 0 (garden tap...

So if we got the mains pipe replaced, then what are our options? are they still: -Just a big combi alone -heat only boiler + megoflo type unvented tank -combi + accumulator tank ??

And just in... first confirmed quote from a Moling Co for 15m length of mains replacement. £630

Happy Plumber - thanks - that makes very logical sense - the simpler something is, the least likely it is to go wrong. I just bought a gauge and measured as follows: Measuring garden tap alone - 4 bar, and when I turned on kitchen tap, the garden tap pressure went up to 7bar. What...
