How to Set an Altitude Valve

[Will007]

Hi,

Anyone familiar with setting altitude valves.

This is a 1-way Watts ACV Flow altitude valve Mustang Series Model M127-1.

Anyone know how to go about setting this altitude valve to control two tanks at different elevation.

It has to shut off lower tank when full to push water back up to upper tank, then opens when lower tank is half full.

Thanks in advance for any help you can give.

Does it have a digital meter that'll show you what your High Water & Low Water settings are?

You need to install pressure gauges to know what the water levels are.
