I have a 1.5" sump pump discharge pipe that comes out of my basement
above ground. See photo at:
It them goes underground into a 4" PVC pipe for about 8 feet. Then
it makes a 90 degree turn and runs along the back of the house past our
garage. At this point it makes another 90 degree turn and takes about
a 60 foot run to the storm drain in the street. The total length of
pipe is 130 feet.
My original problem was that the joint at the first 90 degree turn was
seeping water. This went on for about a year and I slowly began to see
the pipe as the dirt and grass were washed away. Then I noticed the
pipe was cracked.
I immediately called a plumber. They came out and discovered the pipe
was cracked from the house to the first 90 degree turn. The replaced
this length of pipe for $350 (the union rate is $120 per hour plus
parts). They then ran water down the pipe and it flowed for 10 minutes
with no problem. Then it began to pool at the first 90 degree turn.
They told me I needed a camera inspection of the pipe to determine
whether it was being caused by a blockage or pitch problem.
The next day they came with the camera and charged me $275. They said
there is no blockage and that there is not enough pitch in the pipe for
the water to make it to the street and it would freeze in the winter
time and re-crack the pipe. They said the pipe needs to be dug out and
a new pipe buried deeper with more of a pitch. They have given me an
estimate of $5000 to complete this. To say the least I suffered
At this point my plan is to ride out winter and see what happens.
While I am no handyman, I figure to save $5000 I can get some people to
help me in the spring and dig it out ourselves.
Can anyone give me their opinion of my situation and the validity of
the plumber's assessment?
