We had run into a unmovable clog working with a drain clearing company. Since there was no cleanout that we could locate, our access to the line was limited to the vent and was preventing a successful clearing. I was afraid that we might have to excavate. The drain clearing co called Jay from Rickert, (as they work together sometimes) just to stop by and give an opinion and perhaps a quote. Jay and his colleague stopped by looked at everything. Then we went out front. In the one 4 square inch area that we hadn't kicked around, Jay finds a partially buried cleanout. Total game changer for my situation. No charge. Didn't even want to take a tip. The drain cleaning company came back out, we went in again, but now through the newly located clean out. Problem now solved. Jay, thanks so much again. Now that the drain is clear, we don't need his services (yet), but if and when we do, we know who we'll be calling!
