How to Ensure Your Rain Barrel Has Enough Water Pressure

Rain Barrel Elevation PSI 

One of the most overlooked aspects of using collected rainwater is the amount of water pressure it requires to successfully feed from the barrel to a garden’s irrigation system. We are often concerned mostly with collecting the water, its cleanliness, and installing the collection/distribution system, that it’s easy to overlook the water movement. It’s not entirely our fault; we are accustomed to faucets that provide pressurized water practically everywhere in the U.S.

Collecting rainwater to water your garden is a capital idea. It’s affordable, practical, and a critical practice for those who experience annual, long-term droughts. Before buying a rain barrel, let’s look at a few important tips.

Collecting Rainwater: What Type of Barrel

First, you need a rain barrel. To be safer and ensure the water isn’t polluted by the material, find a food safe barrel. These are made from dense polyethylene, which has been deemed safe by the FDA. Containers made of other materials, like wood or metal, can be used but are more prone (depending upon the material) to rot and rust. Often a rain barrel will have a polyethylene core and wood/metal exterior for visual appeal and personal style.

The barrel should also be on the larger side; at least 50 gallons. This is for multiple reasons:



The higher the water level in a rain barrel the incrementally higher the pressure (we’ll explain this more in detail).

Too bad that there are not Taller pedestals, or mounts that enable mounting the rainbarrel closer to the gutter.

I have been using 3 ea 55gal rain barrels for ten years and they are all raised by concrete blocks. My garden is on a slight slope so 1 barrel is approx 6ft above the garden and the other 2 even with it. Using the higher gives a small gravity flow through a garden hose but very little pressure. THe others need using my adopted pond pump. This year I am going to use a "Hydrashot" 20v battery operated power cleaher by WORX to draw water from my barrels. .It provides five spray angles to let you switch from a light shower spray for watering, to a targeted spray for routine cleaning. This should eliminate carrying water buckets and associated work...Italiantoy in MO.
