Query: Good pump for the money

The RIO HF series of pumps is an excellent value. I just replaced my old RIO 20HF with a new one after several years of faithful service. They run quietly, have low energy consumption and can push a large volume of water.Sure there are better pumps, but those are going to cost you quite a bit more money. It is really hard to beat the value of these pumps especially considering the amount of use I got out of them.My only real negative is that these pumps do seem to give off quite a bit of heat into the water. I don't have anything to compare this against though.Overall, I have been very pleased with all the RIO pumps that I have owned.
