The First sump under our sons room (installed by clean crawlspace) has been going strong for 5 years. We expect the New one under the kitchen area (which replaces the cheap quality "joke" we had installed by a private plumber, earlier) will last just as long or longer.. My advice is to hire only someone who does this work every day as their specialty, like clean crawlspace !
The only company we will call for under the house drainage stuff.
jolly good fellows
friendly, and willing to answer questions, for understanding.
Looks good to me, on outside.
Have not been under house to take a look. I expect it is probably just as clean, from what i see outside.
