well piping
well piping
(OP)
I am designing a well house. I will be pumping from a well to a pressure tank. I will have a check valve and a meter. Any reason to have a gate valve too? I am considering one downstream of check valve and meter and upstream of pressure tank. That way I could isolate meter from tank in order to replace meter. Does this sound like the right place to put it? Do I even need a gate valve?





RE: well piping
You can always construct with a minimum of valves, depending on what you will accept as risk and work with running and maintenance.
Depeniding on pressure and size (suction or pressure from well) pump type and tank, and what valves (check and isolating and PSVs) that are already included in tank and pump supply you could discuss following points from tank downstream:
checkvalve for tank
isolating valve for tank
PSV for line, isolating valve for PSV
air inlet/outlet valve (rupture and filling/emptying of pipeline)
isolating valve for air inlet
isolating valves before and after pump
pump PSV if not supplied
isolating valve for well
checkvalve before or after pump as necessary
drainage valve before and/or after pump as necessary
strainer(s) if impurities are possible from well, with drainage or cleaning possibillities.
... but then this is of course the 'full package' for a professional lay-out.
Start with the list and consider what you could be without.
Good luck!

Second in most states they do not allow a check valve in the house. The reson behind it is that if the pipe between the well and the house broke the check valve in the house would allow the line to depressurize. The hole could allow grond water into the line and then when the pump starts again the contaminated water will bo pushed/sucked in the house.

While I agree the diagram is normal, that very complucated for a residential well application.
Surcharged,
Why are you putting in a meter in the first place? Is it required by local code?
