Jet pump configuration for lake use at cottage ?
John
is re-using a Duro 1/2 hp pump from a friend. It was set up at his
place in a deep well application with the ejector / venturi unit in
his well using a two hose connection between the well and the pump
inside his cottage.
His handyman disposed of the ejector so I ended up buying a new
universal ejector / venturi unit but it doesn't fit on the pump body,
as one would do in a shallow well/lake application like mine (15'
lift).
The question is whether or not I should use a double pipe to have the
ejector in the lake near the foot valve, or can I just hook it up near
the pump and have just a single pipe to the lake. Are there any
considerations with priming etc?
Your advice is greatly appreciated,
John

I have always thought of you as a rather
intelligent person but now you give me some doubts.
Jet pumps were designed by the devil herself.
They can be one of the most aggravating bit of
machinery ever invented.
One tiny hole in the nine and it won't work. A
hole so small that is can been nearly impossible
to find.
For a 15" lift you should consider a DuroŽ Piston
Pump. They can be noisy but enclose it in an
insulated box. These are like the batteries that
keep going and going. "IF" for some reason an
overhaul is needed one can buy a repair kit for a
few $ and any one with a wrench and screwdriver
can install the new leathers and gaskets in a hour
or so. Unlike a Jet pump the line can leak like a
lawn sprinkler and the old workhorse just keeps on
a pumping.
I have often seen them curbside on pickup days and
I am sure that 99% of them might require a kit at
the most.
You can't kill these beasts.
Suggestion: If you go ahead with the jet pump
place a cursing jar nearby and there is a good
chance you will be able to take an early retirement.

Well I'll be... I assumed piston pumps were ancient and therefore
crappy technology. Apparently not... Well I already have all my bits
and pieces scrounged together (pump was free) so I'll go with it but
will make extra sure to see that it's all sealed up tighter than a
nun's... errr... sealed up really tight.
Thanks OT

Is that like a bull's ass in fly season?

John....what you have here is a 2 line jet pump. they are a cursed
creation of man. They were the technology between single line and
submersible when a deep well application was used. You cannot convert
these cursed beasts into a single line pump as the venturi is designed
to be in the well.
