Well Head (n) The location where the casing of the drilled well reaches the surface.
Most Common Well Head Assemblies
Well Cap vs. Well Seal
Well Seal vs. Pitless Adapter
You can protect your solar well pump from freezing in a few different ways:
- Use a pitless adapter to keep all plumbing lines below the frost line for your area (ask around if you’re not sure what it is where you live).
- Allow the water in the pipe to drain back into the well when the sun goes down and the pump is no longer pumping. The rotor within your RPS solar well pump will allow this to happen. No water in your pipes means no freezing, but the pump will have to work each morning to refill the pipes before you’ll make progress filling your tank. This only works if you do not have a check valve in the system and your pipe from well head to tank is not excessively long or a large diameter.
- If you are going to use a check valve somewhere (necessary in a pressure system or to prevent backflow), add a weep hole below ground level on your drop pipe. This gives the system protection against freezing below the check valve. Anything above the check valve is still at risk of freezing, so place it accordingly.
