The first one on the phone said if he had to look for it, it would be very expensive and didn't act like he was interested in the job at all. Doesn't seem like anyone in this area wants to or has the knowledge to locate.
Sigh. There are a lot of lazy dumbasses out there in the trades, aren't there? And the good plumbers and tradespeople -- the ones who participate here -- make comments and suggestions based on the pride they take in doing the job professionally and running a successful business. The reality out there isn't always as enlightened.
That said, if you have a yellow pages or yp.com, pull it out and look for someone sorta-nearby who isn't Roto Rooter (or any rooter) and is either a plumber or a septic company. Also, try bbb.org. It's old-timey, but I have to tell you Terry and all my favored contractors all have A+ ratings from their local Better Business Bureau. If you have Angie's List, use it. Yelp, too, if it's in your area. You also might PM our contributor MacPlumb, as he knows great drain cleaning folks in so many areas of the country. He recommended one in my area who was awsome. It's a pain to make 10 phone calls, but you would be amazed at the differerent reponses you get from company to company. "Nah, we don't do that." "Yeah, but it would be expensive." "Of course we do that, Sir, and we'll do it at an affordable rate if you give us a chance to have your business over the long haul, and promise to tell your friends if you like our service." Some people get what it takes to run a successful business, some just want the lazy work. Helping someone out when they are frustrated and desperate is the best way to make a customer for life.
Being able to attach a little current-deal to a snake and searching for it with a treasure-finder-type deal is a basic process most good plumbers are happy to do. It's easy and accurate.
