    Gurgling in a Megaflo

    Hi, I recently had an external expansion vessel fitted for our boiler, along with a couple of radiator valve replacements - for which the system needed draining an refilling. I happened to poke my head into the airing cupboard the other day when the HW was operational and heard gurgling...

    Fluidmaster Dual-flush - Periodic 'automatic' refill issue

    Hi, Had some fluidmaster dual-flush kits installed a few months ago. Two are fine, but the third has a problem. If we don't flush it for a number of hours (and, as it's in the en-suite, this tends to happen), it will suddenly start filling for a few seconds, and then stop. I know this...

    Radiators warming up when HW only - dodgy isolation valve ?

    Cloudy hot water from taps

    Hi, Last couple of days, the water coming from the hot taps has been cloudy. This dissipates after 30 secs or so, and agitating the water doesn't make it cloudy again - so, looks like dissolved air. I've an unvented system, with a Heatrae Stadia Megaflo cylinder. Haven't made any changes...

    Any issues with replacing the syphon in 'old' Twyfords WC?

    Moved into a house recently. It's got two styles of Twyfords WC - both closely coupled bottom entry, bottom external overflow, front lever models. I want to replace both styles with new innards, including internal overflow. Talked to the technical support at Twyfords, and was advised that -...

    Pressure slowly dropping in sealed system

    Hi - first post, so please excuse if this is done to death elsewhere ... We've recently moved into a house which has a 9 (?) year old Alpha SY24 system boiler. Given the marks below the vent pipe outside, it's obviously had some issues for a while. From the way that the pressure rapidly rises...
