Question

Sump pump installation


I have decided I need to replace my sad old pedestal pump.

Here is what I have chosen:

Zoeller N57
Verticalmaster switch
Zoeller 507 backup pump

My current hole is 11"x11"x21".

Can anyone give some advice on the minimum dimensions I need to have for the above installation?

I suspect I would be best served putting it in a sump basin; would you agree? Can I get a lid for it that will accept water coming in from above (say a sink leaked in the same room)?

For your info my basement is:

1680sq. feet
Distance from bottom of sump hole to the pipe head (before it turns 90' to exit the building into the gutter downpipe) is 8'5"

The distance from the head to the gutter downpipe is 6'.

If you think I may have underestimated using a 1/3hp model let me know that too.

Thanks,

Morris

Sump pump installation


I'd like to help you, but my knowledge in pumps is not so good.

Sorry

Sump pump installation


Moggi, we have no idea how much water you are trying to keep at bay.
I have some customers that keep up with the water with a wet/dry vac. and others with 4 pumps set at different levels to respond to the change in seasons and weather. A basin can be ordered to any size you want, with and without covers. If you're handy you can make your own out of a garbage can.
Square footage does not help with sizing in this situation. The amount of water coming in does.

I see!

Well currently my pump is cycling on when the sump is half full and it is currently going about 4 minutes between cycles.

At it's peak to date it was cycling about every 2 minutes and yet just last week the sump was dry.

I have only been in the house since November 2006.

I'm not sure how to calculate the volume of water in a sump that is 11x11x21!

As for being handy...err, no

Thanks Pipes.

Ron, no worries, thanks for looking anyway.

Sump pump installation


How many gallons per minute did the old pump eject?

Do your gutter downspouts feed into this pit?

I would try and get all outside downspouts to direct the rain waater from the roof as far away from the house as possible. Better to keep as much water away from the house then to have rely on a pump for all water removal.

Does the ground around the house slope away from the house?

Downspouts direct into a pipe underground that runs out to the street. So when the sump pump pumps out it goes to the same place.

Overall the water does flow away from the house; there are a couple of places on the opposite side to the pump where it doesn't and this will require a new driveway or some patching in the short term.

We do get a lot of runoff into our back garden from other properties and though it doesn't run to the house above ground I am sure some of it finds its way to the footings under ground. I intend to put in a french drain where the runoff comes into the garden and direct the water around and out.

The pump pumps approx. 11 gallons in each cycle and runs for 26 secs.

Sump pump installation


Further to some advice I have ordered the following:

Zoeller N57
Zoeller Unicheck valves
Verticalmaster Switch
Zoeller Aquanot ll backup system
Concorde 1080T Deep Cycle battery 108aH

Once it is all installed I will report back as I have found that knowing how a project went is often helpful.

Thanks.

Sump pump installation


Well; I drilled the sump hole myself with a Bosch Brute on hire from HD.

The clay underneath the concrete caught me by surprise and made the going very tough.

I had already drilled two holes in the driveway for gate posts so was knackered by the end of the day. I ended up drilling 24 of the 30" required. I am plugging away at the balance each day with a small hand trowel.

It was tough going but a lot less expensive than getting someone in; exactly what you might expect.

If you have a soft soil then I would say jsut about anyone could do it. If you have clay then it is going to be hard work.

I should have the back sump installed in a week or so; I will need to hire the Brute again to expand the front hole. Total cost will be appx. $250 versus my best quote of $1600 for driveway and sump installations.

Hey; I may even live longer

Sump pump installation


I'm not familiar with sump pumps and had a question I thought I would just tag on to. I have a sump pump basin in my basement. Normally I don't have much water. However, we have received nearly 3 inches of rain, maybe a little more and I noticed that the pit has filled up to about 6 inches from the basement floor level. Is that normal?

I don't currently have a pump, should I get one?

I don't have any gutters connected to this, so I'm assuming that all the water has come from the ground.
