The I and I passage
From Louis Blazek
Beware home owners of which type of I and I you choose.
Forty-two years ago, when putting in the sanitary sewer line for my new home, I was going to build; next to the house area, I installed a back flow I and I trap. It was a four-inch castiron with a brass flapper that was to let the flow of waste away from the house and stop any flow into the basement.
The first year after we had moved in our new home, a big rain came, and into my basement came sewer water and waste shooting up and out of the shower and stool, putting three to four feet of sewer waste in my basement. I dug down to check that trap and decided it could not hold back all the pressure of the big sewer main.
I then dug out in the yard and installed a second trap made of PVC. That helped for about two years, then failed. I dug it up, and put in a manual shutoff valve that I now have to hand operate to keep out sewer water and rain water. I found when taking out the PVC trap, that a rat had eaten a hole in it, making it fail.
I would like to see the city take that $500 they plan to spend and hire an engineer to show how to correct the storm sewer from getting into the sanitary lines.
I fear what will happen when they start putting new storm and sanitary sewers in that cow pasture west of town. To run all that waste and water into our already undersized and leaking system will cause everybody problems. Maybe we’ll have to end up putting the old two-hole outhouse in our back yards?
