sump pump hose

rusty baker

I get a lot of ground water into the basement of this 100 year old house. Limestone walls. The sump hose runs outside onto the ground. It freezes in the winter. Any way to insulate it?

I'd get a larger discharge hose.

Worse case, route it to your public sewer drain (assuming you don't have a septic system).

My pump will only take a 2" hose. Against code to run into the sewer.

You need to find a way to keep a pretty good pitch on the discharge pipe and to make sure the water does not puddle at the outlet. Running it into the sewer is illegal.

The hose goes straight up 4', then out of the basement and downhill. It freezes inside the wall where it turns downhill.

Two common methods to prevent freezeup of the outlet pipe:

1. Run the pipe up to near the ceiling before penetrating the wall, then make sure the pipe has positive downward pitch after it leaves the house. The idea is to fully drain the pipe every time the pump runs.

2. Run the pipe underground at a slight upward pitch. You can elect not to use a backflow preventer, in which case the water in the pipe will drain backward into the sump pit when the pump stops. Some people install a backflow preventer, but put a small hole in the pipe (typically 1/8 inch) to allow the water to drain after the pump runs. The hole typicall is drilled in the pipe just after the backflow preventer, and faces down so any water forced out of the hole during pumping enters the sump pit.

Either of these techniques will eliminate freezeup since there is no static water left in the line. Of course, if you bury the line below frost depth, you will not have the freezeup problem either.

I know it's against code, but given that choice or water in the basement.....I'd go with......

In any case, if there's no threat of the freezing discharge to block up the 2" pipe, I would not worry about it.

My pipe runs outside, then it dumps directly into a larger 3" pipe
Water seems to be collecting/staying in your pipe causing the problem

Do you have a check valve in place after the pump ?
That will keep water in the pipe

What you can do is bury a long 4" corrugate pipe right at the outlet form your house and extend that pipe, underground, all the way into an exit point.

The 4" pipe would be in the inlet from your direct sump discharge.
