Hi, The flow from all taps (except the nearest to the main stop cock) has recently reduced to very low. Pressure is present for a short time but then reduces. I have an old model of valve 95605869 8 bar with the square body. I am happy to replace it if that is necessary. Can I be sure that is required? The replacement is quoted as 9560583, will this fit without any changes to the existing pipework?
It may be worth trying to clean out the inline strainer built in to the valve first, this is normally a plastic part on the valve and should only take 15 minutes to do
