Determining System Type

A siphoning system is a plastic tank with a flat lid and a clear tube that connects to your above ground well pump. The pump is usually large and has pipe running into the ground.

An injection system usually consists of a plastic tank with a small injection pump drawing solution from the tank and injecting it into the irrigation piping.

Flow Rate in GPM

Determining Flow Rate

We measure irrigation system flow in gallons per minute (gpm). What is the maximum flow rate of your irrigation system in gallons per minute? Please ask your irrigation specialist or feel free to estimate.

How to Estimate Flow Rate

To estimate your flow rate you will need to determine what your largest zone is. This would be the zone with the most sprinkler heads. Count up the number of heads in that zone and multiply that number by 3. This is the number you will use for this section.

Determining Tank Size

30 gallon tanks are the size of a brine tank or utility trash can and have a drain spout on the bottom. 65 gallon tanks are large transparent tanks with a lid that looks like a "flying saucer." 100 gallon tanks are very large and look like an igloo with a black lid on top.

Determining Iron Level

Unfortunately this isn’t something we can guesstimate. You must have your water tested to find this out. There are 3 ways to have your water tested:

• Call your local irrigation or water treatment specialist.
• You can use the "Do It Yourself" test kit that came with your new feeder system or purchase one from www.cleanwatercart.com and test the water yourself.
• We can test it. Download the Well Water Analysis Form from the support section of our website. Fill that out to the best of your ability and mail that back to us with 4 ounces of water taken directly from your sprinkler head.

Determining Pump Output

Stenner Pumps have a plate on the side of the base. The Gallon Per Day (GPD) of the pump is listed in the lower right hand box on this plate. Use this number for your calculations and ensure that if you have an adjustable rate pump, that the arrow is pointing to the 5 (50%).

Neptune Pumps have a plate on the back and have to be identified by their part number. PZ31 is an 11 GPD pump and the PZ61 is a 22 GPD pump. Use this number for your calculations and ensure that the dial is set to 5 (50%).

LMI Pumps have a plate on the back and have to be identified by their model number. P03 is a 10 GPD pump and the P05 is a 24 GPD pump. Use this number for your calculations and ensure that the dial is set to 5 (50%).
