My back yard rain drainage is getting clogged frequently.
I already know the reason because I have tried to fix it and had cut
concrete and have seen the whole picture.
The drainage system was done first at the time the house was buitl,
and most probably was done properly.
But later, probably 2-3 years later the pool was built and the piping
for the pool was done in such way that it has pushed the drainage
flexible pipe in one spot down. So, the flexible drainage pipe in this
spot makes like a U letter and goes down below pool ppe and up again.
With the time; house is about 25 years old now and couple years ago I
have seen first time when the rain was very strong the water started
to accumulate in the yard. I had to manually dispose the water and
pump it out of the yard during high rains.
We have cut concrete, changed the flexible drain pipe and it was OK
for 2 years. Not, seems same problem it is just not that bad yet.
What can be done? To redo pool piping will cost thousands of dollars.
