Lake Irrigation Question

[BS Frank]

Thank you in advance for your assistance.

New lake home and looking to accomplish the following:

I have a red lion rl-sprk100 pump. I would like to suck water from the lake 20' away from the pump and about 5' below the pump to a spigot location 20' away from the pump and about 10' above the pump. Would like to be able turn water on/off at the spigot. Already have sufficient electrical set-up available. Looking for any assistance specific to cycling of pump, etc. Thank you!

Those pumps are not really made to work with a pressure switch and tank. After lifting 5' that pump will build a max pressure of about 42 PSI. Even a 20/40 pressure switch is working too close to the deadhead pressure of that pump. Jet pumps build enough pressure to use a 30/50 or even a 40/60 switch and a pressure tank. Sprinkler pumps are made to run sprinklers at low pressure/high volume and need to use a pump start relay or be manually turned on and off.

Thank you! Is there a specific pump you'd recommend for this application?

Red Lion also makes a "jet pump" which is the key. The jet almost doubles the pressure compared to a straight centrifugal. Any jet pump with a max pressure of at least 60 PSI will work. Better to use a submersible if possible. Those cheap 1HP, 33 GPM pumps make for a good lake or cistern pump.
