Hi all,

Last Friday I had a strong rainfall and after several hours I heard my backup sump pump alarm buzzing ... so I went to check it and I could see both main pump (1/3 HP) and backup pump (battery operated ) working continuously !!! with the water level almost at the edge of my sump pit (about 20 inch diameter and about 26 inch deep). The water was coming in from the 2 weeping tile pipes at a very high flow rate. Fortunately, I had a 1/2 HP pump available since I planned to replace the current 1/3 HP and 5 years old main pump ... so I just connected a flex discharged pipe to it (out to my garage) and helped the sump pit for 30-40 minutes or so ? until the power went off just to amplify my terror ! So here I’m, with a flash light in my month, and manually helping the backup pump to keep up with the flow ... I believe I have more white hair now! It stopped raining in the meantime + the power came on and off ... but I manage to avoid a flood in my basement. Next day in the afternoon I checked with some other neighbours (they have a 2-story house too) and I was amazed that no water was coming in their pit at all ! I went back and checked my pit again and the main pump was cycling every other 2-3 min. but no water was coming from the 2 weeping tile pipes, but rather from beneath one of them only ! (there is a gap around both drain pipes ) Is this the water table ???. Other note: there is water under my sump pit black liner bottom. As far as I know my pumps discharge to a city storm system and I have weeping tiles around the house. All my downspouts have 4 foot of extension, the back of the house has a concrete patio, the half of the front is protected by the garage, and both sides of the house are having landscape with a bad grade I think now ... So far it seems that the rainfall combined with a rising water table just overflowed my pumps and pit for a while. !? What do you think ?

I’m looking for your opinion on next issues:

1.I’ll replace the 1/3 pump with the 1/2 HP . My discharge pipe to city storm system is 1 ½ inch pipe. If I also connect the old 1/3 pump, will this line be able to handle all the pumps ? Or I should discharge one of them to outside driveway ?

2.Why do I have water under the sump pit liner ? Is that ok ? what can I do about it ?

3.Why I still have water coming from the gap bellow one of the weeping tile pipe ? I’m draining the water table ? What if I seal all these gaps and I’ll have only the weeping tile pipes to bring the water in ? Any negative effect on the foundation or basement floor ?

4.Should I do something about house sides in terms of the bad grade ? Left side has only grass and no concrete around and the right side has little evergreen trees with mulch and a concrete side walk ; the mulch level is bellow the side walk and I seems to be a good water trap/reservoir next to my wall ! Any ideas how can I change this situation and slope the grade away from house, or seal these zones ??

5.The house is 10 years old and I owned it for the last 6 years. In my first 4 years I had no problem but a similar situation happened last year in July! How strange is this? How come my neighbours have no similar problem?

6.I’ll verify the check valves too.

Your help is highly appreciated since I don’t think I can survive a third experience like this ... now I don’t really know what to do since I don’t know the root cause !

Many thanks in advance !!

Did you ever figure out where the water was coming from? I have exact same problem

Thank you

I have the same problem. I get constant water flow into the sump pit of the house we just bought. The sump keeps up but runs about every 1 minute. Besides running up the electric bill I am concerned that if there is a power outage we will have a flooded finished basement because I have tested the battery backup pump and it won't keep up with the flow. I could really use some advice here. BTW it hasn't rained in our area for over a week but it is spring here near Columbus, Ohio, will the thawing of the ground in spring cause this much water to end up in the sump pit?

BV have you ascertained where the pump is discharging to? If there isn't enough clearance, like a hose attached to take the water away from your foundation, you could just be recycling the same water which is why it would be on every minute.

Also ensure roof drains aren't leaking into the foundation area.

You might also want to backfill a little more around the foundation or check the slope of your yard. If the soil has settled and you have low areas, that could be a problem. Also check to see if your neighbours' pumps are draining onto your property causing an issue.

Check out a company called SEC America. They make a device called Pump Sentry in two different sizes.

It is basically a converter of sorts. It connects to one or more marine batteries in series (I think up to three or four together) and converts their power so that it can power the MAIN pumps. No little 12V backup pumps. Get a couple of these and a couple of really good deep cycle marine batteries and your pump(s) might be able to work for an entire day or more without power. There is a formula on their website that will tell you how to calculate the run time of one or more batteries with your pump's power rating. This will ease your fear of losing power, as your main pumps keep working. It switches over automatically as soon as you lose power. No work on your part. When power comes back on, it switches it back to normal, then begins recharging the batteries.

If you get a submersible pump like the iON Storm PRO 1/2HP or 3/4HP, they are made to basically run at a lower amount of amps compared to most submersible pumps their size. They are quite reliable and have different switches that you can use with them, including floatless switches. They also pump out a ton of water. 3/4HP can put out nearly 4,500 gallons at 10 feet of head. It uses half of the amount of amps that most sump pumps use in doing that, as well.

You either have a severe property drainage problem, possibly some type of aquifer or underground stream/spring, etc. Research land maps at the courthouse and any local history center that you have. Try to look at the developer's plat maps and see if you can see any drains, storm drains, anything covered over or diverted in your area like a creek or stream, etc. Check for any easements on the land, as well.

Has anyone figured out a solution to this issue. I just found this discussion and have the exact same issue!!! I have spent alot of money rerouting drainage, downspouts etc and am still having alot of water coming in from under the tiles in that gap. I am about to have a nervous breakdown amd am fearing spring! Any help or advice would be amazing!

Our pump (3/4 hp) runs a lot. while digging post holes for a shed foundation I found the water table to be about 2 feet below grade. If we have a dry summer the pump runs less. We have a backup pump as well and keep it maintained.

Pump may be coming loose from mounting plate or foundation may not be sufficiently rigid. Tighten or reinforce as needed.
Impeller may be damaged and need replacing
Clean out any foreign material in pump
