Since we had new toilet/heating fitted the plumbing makes a release noise similar to the toilet flushing or filling. It lasts for a couple of seconds. During this there does not appear to be any water run in the toilet. The en suite and main bathroom are back to back and it sounds like one goes then seconds later the other one goes. It does not appear to be coming from the heating system as I have tried that release valve. It can happen a few times a day but more likely a few times an hour through the night. Any help would be appreciated.
Could be syphone letting by some toilets dnt have over flows they terminate into bowl check to see if bowl is letting water through via bowl
