I'm installing an air ring main round the shed and it'll have water trap drop pipes. One of these will be behind the blasting cabinet and mildly difficult to access. I'd like a press valve on it, something I can prod at with a broom handle, rather than a lever valve. Does such a thing exist? I can google but it throws up lots of push fit fittings, rather than the valve operating mechanism. Similar to a non percussive push tap, as seen in public toilets, but without a time delayed close. IoT wifi connected devices are right out BTW.
