Unless I just happened to get a really horrible defective unit - this product is terrible. leaks from the top where it has the part that turns it on or off (not the places you connect it to the pipe) so there is nothing you can do about it. I had the original U25 before and it was fine, but assuming I could replace it with the U25E was apparently wrong, and I ended up with a similar style Whirlpool unit instead. After getting really really soaked in cold water, a lot, in the middle of winter.
