Gaskets & Seals
Gaskets and seals are needed to prevent the water in the wet end (impeller) from getting into the dry end (motor).
Poor seals can often cause leaks in spas and hot tubs. Always change the pump seal assembly if the motor is serviced or replaced. A leak that reaches the shaft of the motor will corrode it and ruin the whole motor mechanism. Check regularly around the pump for signs of leaks - this can indicate pump seal failure and if caught early you can replace the seals before motor damage occurs.
