Advice needed regarding surestop swich

[Julie Street]

A customer of mine had the same problem which also tended to occur in the early hours, maybe due to pressure changes of unknown cause in the incoming mains. Banging was under the floorboards. Anyway I eventually traced it to the ceramic disc cartridges in the kitchen tap, changed them, problem solved, its worth checking any quarter turn taps you have.

Is your hot water or heating set to come on at 5.40am via a timer or a programmer? If so this could be your problem.

As to SureStop switches, the first incarnation was replaced by an updated version. I've never had any problem with any SureStop installations, although I did replace a diy customer's install as he fitted it to 3/4" Imperial copper, when it should be 22mm metric connections and I'm not a big fan of pushfit connections either.

SureStop water switches are something I install mainly on residential caravans as they provide the user with an easy way of isolating the water supply when they leave.

Thanks for the replies. No I don't use the timer and everything is turned off overnight except the surestop. It's odd why it's about the same time. It was 10 mins earlier this morning, 5.30. I'm asking a plumber to check everything for me next week, and I've made a note of all the pointers here. Thanks!
