Rated 1 out of 5Â by Desertdog Would not recommend.
Can't say as I am very happy with this pump. I went through 3 in one season. I completely protected the pump from water yet had plenty of air for cooling. They still burned up. The cost is high per unit. It's much cheaper to use a bleed off. Admittedly, living in Phoenix during the summer puts a lot of work on the pump but 3 in one season . . . I don't think so. F.Y.I. the regular pump continues working great season after season.

Rated 5 out of 5Â by hotrod351 purge pump
installed it yesterday and it works great. you need to make sure that you have a main pump that will still pump water when its down to 1/2 inch in the tray because the purge pump pumps it down that far, but then most newer swamp coolers have that feature on there pumps. ill know in a month if it makes a difference in the pads.

Rated 1 out of 5Â by Mugwumps Good Idea poor execution
I have been a Desert Rat for over 40 years so I know evaporative coolers. We all hate scale build up, But this is not the product to lessen it.
1. I have owned this for over 3 months to give it a chance.
2. My water bill has DOUBLED
3. It has NOT lessened scale build up. In fact it is worse.
This pump drains the pan for 7-8 minuets every 8 hours. The only adjustment is by using an optional drain clamp. Even with the clamp almost totally closed your pads still get dried out, which causes more scale build up.
For the price of this pump there should be a time adjustment for the length of purge and time adjustment between purges. Maybe if these functions are included in the next model I will give it a try. Meanwhile this one is going back.

Rated 1 out of 5Â by BobinNM Only lasted 2 months
I purchased one of these pumps last summer, and it lasted about 2 months. Waste of money. The timer mechanism is mechanical, all gears similar to an old watch. Perhaps an electronic timer would make this a better product. They are expensive, and junk.
