I needed this pump for my septic tank. It started on the very first pull and performed beautifully each time I have used it. This pump is relative quiet really moves the water. I highly recommend this Honda pump. Can't say enough good things about it.

Excellent pump, BUT...

This is an excellent pump.  I bought it from a Honda dealer to replace an older off brand 2" pump.  It pumps about 7% more water than the old pump while using about half the fuel the old one did.  It's lightweight, easy to hook up, and to start.  The only complaint I have is the two original water plugs for prime and drain were the wrong thread, and very difficult to remove and tighten, even the first time I used it, and I have experience.  The dealer sent me two new plugs, and they screw in and out easily, and work well.  I think it was a factory mistake on the threading of the original plugs.  The thread on the originals was a little different than the replacement plugs the dealer sent me.

Other than that one problem, it's a great pump from a great dealer, Honda of Russelleville.
