Hey all. I have a pond way up in my woods, upslope, and I use a 1/2 poly tube to gravity feed irrigation to my market garden.

I'd like to increase the pressure just a tad bit.

There's NO way I'm gonna get an electric pump way up there in the woods (no electrical line...yet). I need to PULL the water, rather than PUSH it.

Any suggestions for a small electric pump that can do that? Doesn't have to be strong. Just a few PSI increase.

Alternatively, anyone familiar with any settups that anyone has done with solar and battery and small pumps?

Thanks!

A 20W RV pump for $5 will do this

If you replace the pipe with a bigger one you will be amazed.
At least 1 inch possibly bigger if you can afford it.
If you put a ball valve at the bottom and have the pipe run as a syphon, no pump
will be needed and you can control it simply by using the valve.
An air pocket may form at the high point which can stop flow, by installing a small air valve that can be fixed.

So an RV pump is designed to pull water rather than push? Or perhaps is it that it's so cheap that burning it out is acceptable?

No. The water is flowing already with no pump,, the pipe into the rv pump will not be dry.

a $5 rv pump ?    I'd love to know where to find one this cheap!    

I have a similar need to just give my 55 gal rain barrels a boost through 50 ft hose in the garden.   They work fine when full but lose pressure as the water level goes down between rains.

Ok, so a 20 watt RV pump at the pull side of a very long 1/2 inch pipe being gravity fed from a pond will add just enough additional pressure to give me the boost I need (how much boost I need is a matter for another thought...).

I'm gonna try out something from Amazon and see if it works.

Question: do you think this size pump is capable of also starting the water flow effect to begin with?
