We were out today to do our annual home inspection In the hall bath, sink is slow to drain. Recommend snaking the drain. In the utility room, customer concerned the sink is slow draining. Filled and drained sink multiple times, seems to be draining as it should. Did find a small leak on the nut attaching the drainage to the basket strainer. Customer decided to clear the drain and tighten the nut on the basket strainer. Ran hand top to clear sink. Fill and drained sink multiple times to check for leaks and functionality, everything is operating as it should. No warranty on drain cleaning. Nut attaching drainage to basket strainer was only on by one thread. Removed nut and the tubular extension. Cleaned threads on strainer and applied pipe dope. Hooked everything back up and checked for leaks, found none.
