Author Info Ironwood MichiganProduct Tags: Flexible CouplingsStock Couplings Quote Hi, I have used your products several times to save my butt and they have always been up to the job and beyond ; once I had a sink pipe brake in my basement and almost had several feet of septic water in my basement in Feb. in Upper Michigan . Your product saved the day. I remembered that I had a Fernco in the garage ,ran and got it and stopped the rush of very brown water at a spaying pressure..Now to get to the point you guys have to have an application to save the Gulf Coast's and B.P. 's -- get the point a super Fernco with several easy to close clamps and a valve and pipe threads after the shut off valve. Come on you guys can save the Gulf of Mexico . Hope to hear from you guys .. Great proudcts from a great company.
