Hi. My wife and I recently purchased a small off-grid cabin on our local river. The cabin is small (1 bedroom) and we plan to use it for recreational purposes only for short weekend or holiday trips. The water situation is currently a 275 gallon agricultural water tank. We pump water from the river to fill the tank which is located on a hill above the cabin and gravity feeds the cabin. This works pretty well, however the water pressure is not that great, especially for the shower.
I’ve been thinking of installing a water pressure booster pump that would kick on when it detects water flow. Has anyone done anything like this? Any suggestions for a low budget pump?

I can think of no reason you couldn't install an RV pump like THIS Shurflo pump to boost your pressure. Many of us here use that same pump for cistern systems similar to yours... my cistern sits level with the cabin so little or no inlet pressure.

My tank is also above the cabin. I have the same pump Nobs linked. I get decent enough flow without it on for hand washing, tooth brushes, toilet flush.. I have a toggle switch in the bathroom to turn the pump on for higher pressure and flow (shower mainly).

I have something similar to the link but 2.9gpm..I wish it was more because it does drop pressure at higher flow.

I’m currently running everything but AC with solar panels/battery bank/inverter.

If you use a 12v battery bank no worries, just wire the pump into that with appropriate switch/fuse. If 24v or 48v you can use a transformer to convert 120vac to 12vdc. Some find a laptop power supply will work, just be sure it will support ~10amp draw. I have had good luck with THIS cheap 10amp transformer. I do keep a backup but the one I'm using has lasted 3 years so far. You can get these RV pumps in 120vac but folks on here that have used the ac versions claim the DC pumps will last a lot longer.

They make these small pumps in 120v versions also. They cost about the same. No transformer needed.
