Pump A Way Manual Non-Submersible Hand Pump

I'm in the process of rerouting some older pipes from my lawn sprinkler system. I spent a couple hours doing today pumping out muddy water from several holes. Worked great!

Its the diaphragm inside rubbing on the interior walls of the pump. It sounds weird but its perfectly fine. Thats what its supposed to do.

if you have water seepage in your pit and there is an outage this will not move it fast enough. I recommenced an electric boat bilge pump. they are about the size of a softball and run on a car battery some will exceed 1000 (one thousand) gallons of water per hour. You can also find something similar at home depot that is more for this purpose running on a batter. the boat bilge pump will be around 40.00 or less using a 3/4 in garden hose. and the home depot would be similar just better constructed for the home.

No. You have to pump the handle every time to get the water to flow out. Instructions says 1 Gallon is in 4 pumps.

About 6 foot

if it fits in the hole, I don't see why not

Yes and it doesn't seem to clog easily.

Flexible hose from a central vacuum system will hook right up to the discharge hose on the pump

I have not measured the tube opening but I believe it is only 2 inches. you could add a simple pvc reducer and that would guarantee a good fit and keep the performance.

The device appears to be made from plastics and rubber and I suspect the gasoline will dry out and harden the rubber in particular which is what would be around the plunger. There are devices similar to this that are made for gasoline and can be purchased at automotive parts outlets.
