Water pressure

So, what is the minimum pressure they are obliged to provide? I would expect to find this on the OFWAT site. My net connection is currently very bad so can't look myself. Who is the regulatory authority in this case? OFWAT. Can you buy something to measure pressure at the kitchen tap or would a L/min flow rate be as good? I think they are only obliged to provide a static pressure of around 4 or 5 bar. There are too many variables for a l/min flow to be a useful measure. But having said that I do have a vague memory that the kitchen tap should be able to produce xl/min... I am thinking that maybe a series of readings taken over a long period may help to get something done. I would expect them to install their own monitoring kit rather than rely on customer readings. The power companies will if you complain about the voltage being out of spec. Probably have to jump up and down on the right person though. When I couldn't find our external stopcock and suspected low pressure the Water Inspector who came out was very helpful. -- Cheers Dave. pam is missing e-mail |

Now back: http://www.ofwat.gov.uk/aptrix/ofwat...t/poorpressure Gives the details, need less to say I was miles out. B-) The minimum is 0.7bar, or 7 metres head. At the boundary stop tap the water companies have to tell OFWAT about those properties with less than 10 metres head with a flow of 9l/min. My interpretation of that wording is 10metres head when drawing 9l/min not able to supply 9l/min at a much lower pressure but have a static head 10M. -- Cheers Dave. pam is missing e-mail |

Water pressure
"stuart noble" wrote in message ... I'm trying to gather information for someone in Berks about their low mains water pressure. They share a supply with a local school and the water company only comes to measure the pressure during the school holidays when it is judged to be adequate, but only just apparently. I suspect over the year it may not be. So, what is the minimum pressure they are obliged to provide? Is this supposed to be an average pressure over a certain period? Who is the regulatory authority in this case? Can you buy something to measure pressure at the kitchen tap or would a L/min flow rate be as good? I am thinking that maybe a series of readings taken over a long period may help to get something done. If anyone has "taken on" a water utility in this way I'd be grateful for any information. I was in my local Plumb Centre the other day and recall seeing a "Regin" pressure test kit which is basically a dial gauge with a short hose and a washing machine tap connector all for around fifteen quid or so. If you fit one to the cold feed to the washing machine and read and record the pressures over a period you will have a basis for argument. You could go to the extent of fitting a pressure transducer and a chart recorder but its probably a bit OTT at this stage. |
