    Re: What is it?

    hey there,
    it is a old water driven sump pump.
    it uses city water pressure to create a siphon to pump out the crock.
    im not sure how to spell the name brand but its penberthy i think
    i see these still in service around here.

    thanks
    Larry

      So what do the numbers on the armature indicate?

        Looks like Penberthy is part of Tyco now.

        I think the arm is to set the operating pressure for the city water.

          Re: What is it?

          i have never installed one of these so i dont know if that is an adjustment for
          water pressure or maybe the float height?
          but here is a manual for the newer version it doesn't say anything about the arm that i saw glancing through it.

            Thanks for the manual. Looks like it was issued Sep 1995. I read it and there is reference to a steam and a water powered model. Not much on the lever except a short mention in the disassembly section. Didn't find anything more about it.

              At first I was thinking this is a good way to save $ on electricity, but from reading the manual, (if I'm understanding it correctly???) I gather an equal amount of water has to be introduced as to what needs to be "pumped".

              In other words, 100gal of city water would be needed to remove 100gal of ground water???
              If thats the case then that would be a pretty expensive unit to run.

                I just saw a similar device on "This Old House". They were installing a new one, and said that it pumped 2 gallons for every one gallon of city water. They didn't mention the manufacturer of the one they were using. Your older model might not be quite as good. But they were not installing it as a primary pump, it was a back up to an electric sump pump, in case the power went off-line. In case of a power failure, wasting a bit of water is a better option than flooding the basement or structure.

                Keep in mind that if the property is on a well, using this thing as a backup is not gonna work since the well pump would stop working when the power went out (unless there's a backup generator).

                      Re: What is it?

                      Yes some of the newer models of water powered pumps do pump 2:1
                      But, it still adds extra water to the waste stream and if you and the whole neighborhood is trying to get rid of water is that a good idea?

                      By the time you add on the backflow prevention and the water cost along with sewer fees it's not all that economical.

                      I'll take a Zoeller M-53 any day
                      or, battery backup with an Aquanot II
                      or, standby generator with a Zoeller M-53....

                      Water driven sump pumps would be my last choice!

                          Maybe this would make some sense. How about if you had a windmill to power your main water pump and a storage tank up on a hill? You would use gravity to supply water to this special pump and let it drain downhill into a field or creak. This way you aren't paying much for the supply water and nothing for sewer use fees. Try to think of someone like member BHD out in the country if you can. To be able to have a sump pump that does work during a power failure could really save the day and some big $$$ there.

                          Needless to say BHD has standby generators, but maybe he isn't there to start up the engine or maybe he wants to sleep without the noise and such. ___
