Hello,
I have existing 3" interior/exterior drain tile that leads to a sump pit in the corner of the basement. The old basin was solid black plastic and only had 2 holes for the drain tile to enter, otherwise sealed (no perforations). There was about 3-5" of black, corrugated drain tile coming into the pit for both inlets.
Yesterday I had a new sump basin installed that replaced the existing, along with a new pump and battery backup pump. In order to get the old basin out they had to cut back the 3-5" of drain tile that entered the old basin. With the new basin in place, it looks like the existing corrugated drain tile is about 1/2" short of entering the new basin. It's almost as if the existing drain tile stops JUST short of the new holes in the new basin. In order to "extend" the drain tile into the pit, they put roughly a 5" length (maybe more cannot see) of PVC inside the drain tile so it extends into the openings in the basin. The 3" PVC has fairly large holes drilled in it, and the holes are facing down.
My question is, is this method of "extending" the drain tile into the basin acceptable? The fit is fairly snug between the 3" perforated PVC and the 3" drain tile, but certainly not "water tight". My concern is that some water will leak outside of the basin. The sump basin is set in large crushed rock. Is this cause for concern that I might have some water flowing/leaking out of the drain tile and "missing" the basin?
