Press open 15mm valve

[cheb]

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.

Cant you use a valve that opens when the pressure drops, aka self bleeding

Drop the end down into 8mm nylon push-fit pipe and fittings and locate the valve wherever you can gain easy access to, will perform the same function to remove water.

That was plan B. Probably using as clear a pipe as I can find so I can see if it needs draining.

Hi Cheb,

Following with interest!

I'm planning much the same and have a dislike of plastic. I'm fitting 3/4" Galv, you?

I used 15mm copper, as I can get it easily, John Guest push fit fittings as I'm idle, for the main run and fixed to the wall with hospital clamps. Drop pipes to be decided upon, currently I'm using random bits from the scrap box. I fitted a piece of 1/2" pipe from the bottom of the reservoir to a drain tap, it makes it easier to drain and acts as a sump. Also I prefer to drain into a container rather than spray rusty water all over the floor.

22mm would be overkill, there's only ever me using it. If that changes I can easily upgrade it.

Self bleeding valves are either ouch expensive, or need electricity. Probably both.

Not big bore but if only for draining moisture

Looks interesting, thanks.

You could always fit a truck air tank moisture drain, tie a piece of string to it and your done. Available in bsp so easy to adapt to 15mm copper.

Ah, I'd looked at over pressure valves but they'd spray the water sideways.
