What could be causing a noise in the house like a fog horn?

[Patricia]

Hi, We live in a bungalow. We are awaiting a plumber to check for water hammer but not sure if there are other things that may be causing the noises in our property. There is a booming noise about every 10 seconds followed by an echo. It starts at random times during the day and continues well into the night if not all night. We had solar panels fitted last year along with a ventilation system all up in the loft where we can't see it. We are all electric and use our own plug in heaters rather than the night storage heaters. The cold water gushes out of the taps but there is no spluttering and this noise does not seem related to using anything to do with the plumbing. However could it still be coming from the pipes?

Hello Patricia,

Firstly check your toilet filling valve(s), if the older delchem washer type, then this can produce a loud vibrating noise throughout. Also, do any of your taps drip?

OK thanks. No none of our taps drip ATM.

Did the noise start after the ventilation system was installed, if so get them back.

Yes but what part of the ventilation system could it be? It only started a few months ago not from straight after the vent. system was put in. I don't think it's the toilet because it's not just on flushing and started this morning before the toilet had been flushed.

Try turning your stopcock off at the mains and don’t use any water, and see if it still happens.

I suspect there maybe some backflow preventers/ non return flaps in the ventilation system that are moving around, maybe from wind outside?

Or noise from the ventilation fan, something may have come loose.

We are council so have to wait for a plumber to do the water side of things. I've just arranged for the vent. system to be checked out. Thanks for answering...
