Wet end was leaking. Original O ring was bad. This O Ring stopped my leak. I actually ordered the incorrect part. Spa Guy called me to double check and correct my order as it did not match up with my model pump. Probably the best customer service I have ever received. Any future Hot Tub needs will be from the Spa Guy! Best in the business.
