Glad it worked! Keeping my fingers crossed for you.

We have that rotoruter and most of the time it works great! Would recommend one anyway if you can afford it

Dh's shower has always been slow and usually the rotoruter cuts thru it. But last week was the last straw, DH was tired of crawling on top of the house to work the machine from the upper vent. We had the plumber come out and replace the pipes from under the house. 40 year old cast iron pipes with hard water, and they were nearly completely closed up on the inside. I'm sure it's just a matter of time before we have to replace the rest of the house's pipes, too.
