Hot Water Vessel Permanently Attached Pressure Gauge.

[RayPooley]

Hello everyone.

I want to permanently fit a pressure gauge to the schrader valve on a hot water expansion tank
.
I want to fit an isolation valve first to the schrader valve then fit a gauge to that valve.

The idea is to just open the valve when you want to check the pressure and leave it closed by default.

Any suggestions vis a vis the valve and the guage?

Cheers

Can I ask why ?

Can I ask why ?

Elderly lady friend's system.
She lives 15 miles away.
I normally check the HW EV pressure at the schrader with a hand held pump.
Of course I have to be there in order to check it.
It would be useful if she could just turn a valve on and off once or twice a year to check it and
tell me over the phone what the pressure is.
It would save me a 30 mile round trip if it doesn't need attention.

You would have to turn and drain the cold water to assess the pressure

She's ok with that bit.
Mains stopcock and hot taps are easy access.

She's quite handy.

Mains stopcock and hot taps are easy access.

She's 5' 2" and would have to stand on a stool to reach the EV Schrader.

It can be a bit awkward even for me trying to connect the gauge to it.

But if she could just turn a tap on or a lever.

It's just a thought.

I haven't spoken to her about it.

I'm just mulling it over from a feasibility viewpoint.

I can't find any suitable adapters / valves anywhere.

When dealing with the elderly you need to keep in mind that typically (a) they don't like novelty or hassle, (b) they will get older and more infirm with time, (c) one's balance deteriorates with age and standing on a stool, which is never a good idea, can become deadly...

Have you considered fitting a 'tell-tale' pressure gauge, e.g.:

somewhere easy for the customer to see and/or photograph. As the expansion tank loses air, the maximum pressure (that occurs during the heating phase) will gradually rise. Once it gets close to the tank manufacturer's recommended limit, it's time for a visit.

The lady is my ex wife. Known her for 50 years. She's fine.

Tell-tale gauge would be a good idea.

There is one fitted between the CH system and the CH EV.
However that's on the water side of the EV membrane/bladder.

What I am talking about is attaching an air pressure gauge to the schrader valve on the air side of the HW EV membrane/bladder. Not directly because I figure there needs to be a water tight valve between the EV and the pressure gauge that should remain closed in case the EV membrane/bladder should fail.

It would probably be a while before anyone noticed should that happen.
