“I had to replace an old Waterco Safety Suction 50mm Slip Fit for a Concrete spa. I saw a generic 50mm Safety Suction slip at the local pool shop but it looked pretty flimsy. I looked on line and saw that Direct pool supplies sold the Waterco Safety Suction 50mm Slip Fit that i wanted. It was very easy to order it online and it was delivered in a few days. Very happy with the quality of the part.”
