Part # 5110-62
Manufacturer Code SPX1600PN
Alternate Part #'s SPX1600PN
Hand knob kit for the following Hayward pumps: Max-Flo (since 1993), Super Pump, Sumper Pump VS and Super II. Holds the strainer cover in place. Includes knob and swivel nut.
Concerning the Hayward swivel nut, I always have to replace them. Just about every year they either snap in half or get stripped. When I buy new ones I have to get the handle with it. Don't they sell the nut alone, and do they have any brands that make the nut in metal? I see another type listed by you that is metal, will it fit and work on my Hayward DE filter?
Bob, Unfortunately, they do not sell the nut by itself. The older style was a brass piece but Hayward changed the material to plactic several years ago.
under what circumstances would part # 5110-62 become faulty? i suspect this part is faulty as it is not tightening and the water is escaping?
Likely if the threads are bad from the start and or the knob itself is molded wrong. In the end such a part would need to be deemed defective by the manufacturer though.
I'm thinking of purchasing this replacement part but wanted to know how to remove the old, stripped plastic swivel nut from the pump? Does it just pop out with a little prying? Thanks so much.
You are correct in your assumption that is should just pop out. When they are new, they slide out real easy. As the pump gets older, they do get a little more set in place. A simple tap on the side with a screwdriver should pop it out.
(5 out of 5 stars) Solved Air Leaking Problem
Reviewed By: Joseph T. from Birmingham, Al ()
Pros: quick - easy to replace
Cons: not realizing it was so simple
Leaking air in filter on suction side of pump - so air was getting in water not leaking water out. Gasket was damaged and one screw had been overtightened and threads damaged. ordered, received, and repaired within three days. If you see air bubbles in water to pool this may be your problem
