    Caleffi Pressure reduction valve causing noise

    OK I have recently installed a Caleffi PRV to a 28mm pipe. Incoming pressure I am informed by local plumber is 7 bar and I have reduced this to 3 bar. The trouble is that the prv is causing a nasty vibration/humming noise when using any of the taps or shower down stream of the unit. Any ideas

    Hi all. I've recently been getting regular complaints from customers about their new ecotec plus 615 vus regarding an intermittent loud rumbling noise. Checked high and low co2 ratios, gas inlet pressure etc but never find a cause? I've had Vaillant go back to a few but they dont give me any...

    Chatter at taps and pipe noise

    Hi hope there can be some ideas here. I went to a job oil (heatslave 20/25 combi ) the pipework was chattering or banging very quickly intermittently but especially when cold tap was run at the same time. The flow switch was leaking badly so I changed it and the noise from the pipework stopped...

    Recently moved house and I have a ideal logic 24 combi boiler, it fires up perfectly fine, but when the central heating gets up to temperature it makes a whining noise which can be heard inside but is very loud from the flue terminal. It only lasts maybe 20 seconds or so and comes and goes...

    Noise in radiators (closed system) when hot water run

    Worcester Bosch 37 combi boiler on a closed, two zone heating system which in itself works fine - all radiators hot, quiet etc. However, whenever there is a hot tap or shower run there is a small "gurgle" from one radiator when the tap is turned on, and another much louder "gurgle" around a...

    Boiler Grinding noise on start-up from cold.

    I have a BaxiFS601 that has been running fine for many years, recently began to make grinding/whiring noise at start-up in the morning lasting for around 15mins until it gets hot. I think it may be air in the boiler but all rads are hot and no air in them.

    Worcester boiler droning/rumbling noise

    We've been pleased with our Worcester 36cdi installed in 2013. Over the past few years we noticed a low droning or rumbling noise which gradually increased to the extent that it woke us up in the mornings and pervaded the house whenever the heating was on. Worcester were very helpful and sent...

    Cold water tank noise in purpose built flat

    Hello. I have lived in a top floor flat (block of 4 flats on top of a shop in London) for 2 years and the noise from the filling of the water tank on the flat roof is driving me slowly insane. It’s really loud and radiates through the flat at night like slow running water in an echo chamber...

    Ideal Isar weird noise

    Hi guys, my boiler was doing it since I bought the house a year ago but now it is doing it more often and all night. Before it kicks in it is making a scratching noise, hard to describe. I tried to show to my gas engineer but of course it was fine when he was at my house. Maybe it is normal for...

    Singing noise related to water pump

    Since our central heating system was upgraded in October we have noticed a singing noise in the house when the water circulating pump switches on. It is a new Grundfos UPS2 15-50/60 pump with 3 speeds. Reducing the speed reduces the noise but it doesn't go away, and we need to use the maximum...
