Rated 3 out of 5 by from So so This is the third one of these I have installed in the same sump in about 12 years. It is almost never used but it fails anyway due to passage of time. I think the gallon per hour spec supplied by Wayne is "very optimistic".

Rated 5 out of 5 by from Well thought out kit. Everything reasonable included. Instructions could have advised about the use of ABS/PVC glue if appropriate. Also could have printed the instructions large enough to read.
