Last fall I tackled a little project that could have caused
me big problems. The previous spring, I had a drain tile system installed in my
basement. The system discharges outside, and I quickly tired of looking at that
ugly black extension hose sticking out the side of my house. I decided to bury
a pipe to carry the water out near a rock garden about 20 ft. from the house.
What seemed like an easy, inexpensive project could have turned out to be a
My idea was to extend the existing 1-1/2-in. pipe down into a
4-in. pipe buried 1 to 2 ft. underground. As luck would have it, my
brother-in-law paid us a visit while I was digging my trench. He asked what was
going to happen when the pipes froze in the winter. Unfortunately, I hadn't
thought of that, and every answer I could come up with involved water flooding
He explained that the wise old plumber who worked on the house
he recently built had left a gap between the pipes, so when the water does
freeze it still has a place to go. Not that I didn't believe my brother-in-law (ahem),
but I called the company that installed my drain system to see if this was a
sound plan. They agreed and told me that if I had finished my original design, the
pipes would have likely come apart at the check valve connection, or I would
have burned up my pump. The company said they get dozens of calls a year from
people who neglect to remove the extension hose in the winter, which causes
similar problems. They kindly reminded me they told me as much both verbally
and in a pamphlet, but I didn't mention that I had completely forgotten about
that little tidbit.
I also asked the pros about the water that discharges near the
house instead of out in my yard. They said most pumps don't run in the winter
(which was true at my house), and that a little recycling of water for a couple
of weeks in the spring was better than the alternatives: digging a 4-ft.-deep
trench to get below the frost line, or having water in my basement. I couldn't
argue with that. So it turned out that my brother-in-law saved my skin. It
almost makes up for all those years of him drinking my beer...well, almost.

My sump pump just pumps the grey water (from the wash machine) up into the sewer pipe, and out to the village sewer..
I have a problem-free 1,000 gal septic tank that receives sewage and only sewage from the bathrooms.%0d%0a%0d%0aFor sump pump, I have a Y-drain hooked to a dry well which is nothing but a drum with holes in the sides, buried on side of the house. The other side of the Y junction 1.5" plastic pipe drains outside into a 4" dia extension PVC pipe that sits loose in the back-yard. If the sump faces any resistence, the water automatically drains via the easy path. Never had a freezing problem in the NE. The 4-incher will never be completely filled, being fed by the 1.5". So, even if some water inside the 4" (outside) freezes, there remains plenty of room due to the relatively large diameter.%0d%0a%0d%0aBasement flooding generally occurs when snow and ice thaws - around April in the NE. By then, it is plenty warm enough.%0d%0a%0d%0aBTW: There is no freezing below the frost line - which is why it is recommended for permanent structures.%0d%0a%0d%0abrb
