on cold inlet there is a filter just behind the nut that faces you
too be fair the warranty people at main spares have been excellent, no postage cost no quibble over sending parts, the best customer care i have ever come across, the guy in the the parts is so spot on with his numbers, any way i will check the filter gauzes again.,thanks
sorry but i have to stand up for main 24 he as we have fitted lots ,good value for money ,does what it needs to do and service parts readlly available,backup excellent. theres more to this op thread, under warranty why didnt heateam fix it ?, sounds odd to have to replace so many major items on a new boiler.
hi , because i have, replaced these parts to try and solve this issue, the parts that were replaced are good as spares for me later, to be honest , i dont think there was anything wrong with the parts i replaced,still a hot water delivery pressure issue, what would be a good result doing the (how many lpm in a jug from the hot tap ) cheers
