This is such a great little pump. I am happy to see they are back in stock!
Bought adapter and fit well with existing sand filter. Purchased sandbox sand at lowes, about 1/4 the price. This pump (with suggested adapters) makes a huge difference in the reliability and cleanliness of the pool.
Reviewer noticed a small leak from one of the seals. Corrected issue and fired it up again, no issue. Replacing the worn out innards several times became expensive ($30 a pop) and frustrating.
The spec on this pump says it draws 3. In actuality it is not self-priming, and has a suction height of 0 feet.
They say email the seller. Buyer beware. I wish amazon could vet its suppliers/sellers.
