I have a 10-year-old cultured marble whirlpool bathtub that keeps shooting out black stuff when the pump is on. What can I do?
Cultured marble tubs are plumbed at the installation site and often hold old bath water in the pipes. Try our cleaning process mentioned above, and if the problem persists consider having the unit replaced or re-plumbed to the 100% NAHB drain down standards. All Izzi whirlpool bathtubs meet this standard.
