More Info


Typical installation:

For simple installation of these type of pumps, it will be powered by your water well power supply. This way it only turns on and pumps into your water line when your well pump is on.  To connect to well power supply, you will install an outlet box close to well pressure tank and injection pump installation location. You will run wire from your well pressure switch to the outlet so the outlet is only on when your well pump kicks on.  Then you plug the injection pump directly into that outlet.  Make sure to choose 120v or 220v depending on your power supply available to connect to.

Order of installation would be, well pressure tank, injection pump injecting into your water line, you can inject before or after the well pressure tank. Then after the injection pump and after your well pressure tank, you will want to use a mixing or retention tank to give you the proper contact time of chemical and your water. From the retention tank, you will then go into any backwashing filters you have, or carbon filters to remove excess chemical.

    It was delivered quickly. My well water was at a Ph of 4. With a little trial and error I was able to get the solution mix strength to raise my Ph to 7.4. It’s flirted with 7.8 when I run the hose to fill my pool. With as low of a Ph that I had having to use caustic soda was on the table I was hoping to stay away from that though. I believe I’m at the upper limits of Ph adjustment with this set up using soda ash. I would agree with the one review that the electrical hook up could have some more directions. However my water feels and smells great. It’s only been 2 days for me so that’s the only reason I gave 4 stars. I hope to be able to come back in a couple months and give it 5 stars. I called and spoke with the staff before I ordered and they were helpful. I would recommend this site and the products.

    Great product and a great honest company. I would suggest that you come up with a sizing program to assist customers in dosing and flow calculations. Easy to do in XL. I could have actually used a larger injection pump because my water flows were higher than the norm but instead I throttled back the flow from the well. It all works very well and am very happy with end result.
