We use this to inject soda ash and chlorine into our domestic water supply where we have no access to electricity. Very dependable. Only maintenance required is to occasionally clean the check valve. Only time I've ever had to replace one was when it was destroyed in a forest fire.

Have used Chemilizer HN55 for decades with continual maintenance and parts breaking down. Installed this unit approx 4 years ago and have not touched it in all that time. My use is approx fortnightly for a series of 3 x 12-14 hour periods. Only have to upgrade now as installed new (much larger) pumps and this unit seems to drop the pressure by quite a bit so need a bigger unit. Very happy with it and hope the larger models are just as reliable.

Have 12 of them that worked for 2 weeks in my broiler houses. Waiting for Dosatron to fix them.

This is a great product I have 2 of them now I use in my Greenhouses. Have not had any problems with them.

I have 3 Broiler houses and run medicators almost continually. The Diaphram on all three wore small holes in it after 11 months. The products were warrantied and I got 3 new ones. The company Claims the Diaphrams never wear out and act totally amazed that I have a problem with them. I have found that this diaphram problem is common to most users and last about a year. (No warranty after 1 year) I understand that if the same thing happens to the replacement medicators, I have no warranty now. Hard to find replacement parts for the Diaphram since the company claims they never wear out. Otherwise, the pump works perfectly.
