We are new home owners and we are putting together a list of all the house maintenance we need to do. We came across checking the sump pump to ensure that it is running properly. I have looked up what a sump pum is but do not see anything of that kind in our basement unless it is in the ground. Does evey house have a sump pump and if so, what should I be looking for? We have a dry walk out basement so I am not sure if it is something that was not needed in our house.

The purpose of a sump pump is to pump water put out of a "hole".

With a walk outbasement the foudnation drains can run to daylight.

However, you do want to locat the ends fo the drains and make sure that they remain clear and not burried in the ground.

When I moved into my house there was no sump pump. We started getting water in our basement through the floor due to hydrostatic pressure, and we had to install one.

If your basement is dry, and doesn't get any water even during the heaviest rains, then consider yourself lucky. At the first sign of water infiltration, call a good waterproofing company and have one installed. It's not cheap, and it requires ripping up your basement floor to install the drain tile, but if you get water in your basement, it's the best solution.

Bill -

Saw your reply, and I have a question - I moved into a house with a walkout basement - there was a drain outside the door, I belive it led to a catch basin that went to the sewer (the catch basin was also used for the basement plumbing). I put an addition on the house, and the area outside the old walkout basement was excavated - a new basement was dug attached to the old one, the new basement being a few feet lower than the existing one. The catch basin, which was outside on the side of the house, was removed as it would have been sitting in my new basement. All of my basement plumbing now flows into an ejector pit and overhead sewer.

Soon after our remodeling started, we started getting water in the old (upper) basement due to hydrostatic pressure whenever it rained any significant amount. The old part of the basement was finished - and I'm wondering, was I duped by the previous homeowner, i.e. did he finish the basement and hope for the best until the house sold? Or, did our renovations do something to create the water coming into the old basement, perhaps by excavating the walkout portion of the basement and replacing it with the new, lower part of the basement under our addition?

We've since installed drain tile and a sump pump in the old part of the basement, and the problem is now fixed, but I'm wondering if I might have contributed to the cause in the first place. Thanks.

Specially without knowing your soil condition, type of construction and local building practices.

But let me give you an example of how these problems can be happen. My house is build on a hillside. And the building is stepped. The lowest level has under slab heating ducts.

Now there are several very minor springs in the hillside.

There is black drain pipe that goes around the higher stepped up section along the back and 2 sides (as I found out later).

On the oneside the the drain was extended out downhill and always had a trickle of water and left a swamp. Later I extended down to the lake so I did not see the water.

Then the city installed a new sewer system (with too many screwups to mention, that we learned later) and destroyed the drain line. But that was not know untill recently.

But there where no problems for ahile. Then I started having problems when we had several days of continous rain and then a very hard rain the next day the underfloor ducts would be 1/2 full of water. Pumping it did not do any good. But the next day it would be gone.

Only happened on rare occasions. But it got bad enough that it need fixing.

Started digging up on the other side of the house where the stepped up section meets the lower section. Really with the intend of installing a drain line to draw off any water.

The first thing that we found was a small spring. Just enough to wet the earth. But it was re-aborsed without causing any problems.

But then we found the end of the drain line that was around the upper section.

It was just burried in the backfill.

It have been collecting water from around the upper section, mainly directed there by the gravel driveway, and then dummping it down into the lower section.

We extended that drain line out and down hill to the lake. After rains it would run about 1/3 full. And not a drop inside.

As to your other thread I it does not sound right that you have that heavy a flow and did not have problems before (and I am assuming that the neighbors don't have heavy water problems).

In some areas you do have high water levels, but that is usually know and evident.

I wonder if the gutters where directed into the foundation drain lines? Or maybe the drainlines for that catch basin by the walkout section was distubed and it is not draining water, but the water is working it's way to the foundation drains.

Thank you. I just confirmed with a co-worker whose husband is a contractor. In fact, we do not have one in our house and don't need one. We are fortunate and didn't even know it! Thanks again.

The gutter in the front of the house, and one on the side, used to go right into the ground and then either into the basin and sewer, or into the sewer directly, I'm not sure. I'm so clueless and relied on my builders and the village inspections. The downspout on the side of the house was removed entirely when the addition was put on - we have all new gutters and downspouts on the house. The gutters on the rear have 10' exetensions. The only gutter that spills near the house is on the front - next to my front steps. I put one of those roll out drains on it.

The house, when we moved in, had absolutely no water management at all (save for the walk-out drain and a floor drain). As I noted, we had to completely kill the catch basin to put the addition on, and now the existing floor drain and the kitchen and basement plumbing are connected to an ejector pit in the basement and an overhead sewer. When I started to notice seepage through the floor of the upper part of my basement during heavy or prolonged rains, the only option left was an interior drain tile and new sump pit on the upper section of my basement.

That has solved my problem, $7,500 later, but it certainly works. I was just wondering if our construction did something to create the problem, by removing the walk out drain and catch basin, of if the problem existed but was blissfully ignored. I can imagine the basement didn't at least get a little wet before we moved in (the homeowner did say in the disclosures that the basement had flooded once, but it was when the village was re-doing the water mains).

Like I said, I'm very comfortable with the water management of my upper basement now - we had the drain tile installed in March and haven't had a problem since. I'm inclined to just forget I had the problem and just be happy I did the right thing and the waterproofing company did a good job. I was just curious if I created a problem, or purchased one!

Toddjk: it's obvious that you had a hand in your water problem. The catch basin outside wouldn't have been for show. I'm curious as to how your plumbing contractor got municipal permits because the drawings & specs should have shown the removal. It's your plumbing contractor that should have had to pay to cure the defect & the municipal plumbing inspector should not have approved the removal of the catch basin without the installation of an alternative storm water management system.

I moved into a home without a pump.
Isn't a new home required to have a pump to pass a COO?

Below is what I currently have. Is this for a sub?
