For some reason, doesn’t make sense to me, whirlpool tubs can stop circulating even though the pump is running. Apparently if one takes a clean plunger to the intake, the cover with all the holes, it will begin circulating again. These tubs are designed to self prime. The only reason I could explain this fanominom is blockage in the intake from growth. If one is using soap in the whirlpool I would recommend occasionally bleaching the tub as one would shock a pool. About one quart of bleach in a full tub. Run the motor for a minute or two and let it sit over night. After running the tub once more in the morning to dislodge the remaing growth, rinse the tub and enjoy.
Feed back is the most important measure of customer satisfaction. Without feedback to relate to, a plumber can only guess what most people want or need from their technician. We at Castle Master Mechanical value not only our customer’s opinions but also anyone who loves plumbing as much as us! And some who don't.
