Do you have a stubborn clog in one of your drains that just seems to always come back and at the worst times? One of our recent customers feels your pain. I don’t know how I can thank you. Three times now I have had a clog and it always seems to be a weekend or a holiday when calling a plumber would cost a fortune. But with no fail every time, your product (main line cleaner) has always come thru for me and has saved me a ton of money!!! Like I said, can’t thank you enough!! Amy C.
