Never ever, ever use this company. They are RIP OFF ARTISTS, you will be completely screwed. They charge twice the amount that any other company around. They supply other Aerobic Septic companies their parts in this area, The gal in the office justified the 400% markup by saying "this is the price we charge, you should have checked other companies prices" what bull crap! Maybe I should have, but does that give them the right to price gauge? What a way to run a business, NOT.
