I am looking at adding a basement utility sink. I don't have a floor drain. The main 4" CI exits the house about 2-3 feet above the floor. I already have a washer drain setup but the standpipe is about 6' high. I do have a proper vent and a p-trap and it works fine.
I see the Hartell LTP-1 reservoir pump and this looks like an ideal setup. The tank is small enough to sit under a utility sink. I would remove the standpipe and p-trap. the washer would drain into the utlity sink and the pump takes the water up and out. The lift would be maybe 2 feet....
My question concerns venting the pump resevoir box. The drain line would still have the vent in it right above where the pump discharge would be tied into. I installed a 2" line with a proper vent last year and it is tied into the 4" C.I. Hartell does not show a vent line from the box. Some other's I see do.......Hartell shows a small vent pipe that is dropped into the sink? I am wondering if this is a good system.
I would gain a utility sink.....lose the standpipe that is higher than normal and the whole thing fits in no more space than the utility sink.......I am wondering why some brands show a full sized vent right to the resevoir?
Here is a picture of the existing washer drains.I should mention it is a duplex and has a washer drain setup on each side. I would like to add the utility sinks on both sides.
