The question arises again. I'm looking for feedback on the Sump Buddy (municipal water "powered") as a backup or auxiliary pump for use in power failures (save me getting up every twenty minutes and literally BAILING for twenty minutes, all night!

Windstorm and rainy season is on upon us.............. :eek:

they are all junk

dont trust them


the water operated ones are pretty wimpy,



water operated ones seem to wear out in
the controll valve switch that is triggered
when the water rises....

no one ever gives them exercise,
and you should turn them on at
least once a month to give them exercise

so when they stand dormant for a long time
the switch seems to not work or the bottom of the
controll that is in the water is totally clogged up with
silt and wont "spin" and pump out the water....

itis some sort of "venturi " type of fitting that sits down
in the water with the water hose tied into it and when the
water makes the fitting spin it pumps out the pit too....

its prretty wimpy......

I have put a few in and am not impressed




BUT
If you absolutely have to have anything
but the best I suggest you at least set it up
on a separate line going out of the house.....

DO NOT tie itinto the regular sump line becsuse sometimes the
head pressure is too great for it to overcome and
actually pump water out of the house....depending on what
is going on outside at the other end of the pipe......


just put another pipe out the side of your house
for the emergency back up pump


look at this one, its the best

I can't find any specs on the Sump Buddy but there is quite a bit on Basement Buddy. They seem to spec the water requirements based on only 5 ft of discharge head. At the water supply requirements shown it would cost about $5 per hour for water and sewer charges in my town. Sewer charges because we get charged for sewer based on amount of water used.

The mechanism is not described but it looks like a venturi system and purports to remove 2 gallons of water for each gallon used at 5 ft of head. At 15 ft of head I would guess it will use about 1.5 gallons of water at 50 psi for each gallon removed.

They don't mention backflow preventers but I can't imagine that any public water supplier would want that thing on their system without backflow prevention.

It requires too much water for a well system.

I would go for a battery backup.

The Sump Buddy

Bob , if it is like the ones I have seen it is basically
just a "glorfiied ballcock" with a vaccuum breaker
build in jsut like the old palstic ballcocks have.....


it just sort of has a weight on the bottom of it
hanging down into the pit full of water holding the valve in the off position.

when the water rises the weight or " bouey" lifts
up and trips the spring loaded switch and then the water starts
rushing through the venturi
fitting......

Its almost like a flushing a toilet...upside down??? I guess?
bacisally its about the smae principle.


I have seen a couple that accidentially ran for a a few weeks

because their is no alarm on most of them to tell you they are

running up your water bill sky high.........


but with the head and all, its just best to put it out on
its own drain line stubbed out of the house a few yards
into the grass....I suggest about a 1 inch or 1 1/4 pvc drain is all
