Frequently Asked Questions
What size is the Jandy 4724?
It's the 1.5" x 2" 2-port valve — 1½" pipe inside, 2" pipe outside.
How is the 4724 different from the 4716?
Size only. The 4724 is 1.5" x 2"; the 4716 is the 2" x 2.5" version. Match the valve to your existing pipe — they are not interchangeable.
What's the 3-port equivalent?
The 4715 is the 3-port NeverLube valve in the same 1.5" x 2" size.
What's a 2-port valve for?
On/off shutoff for a single plumbing line — isolating equipment, spa bypasses, solar loops and return line control.
Can it be rebuilt?
Yes — with standard Jandy NeverLube diverter and o-ring kits.
Is it genuine Jandy?
Yes — a genuine Jandy Pro Series (Zodiac) OEM valve.
Frequently asked questions
How do I know which O-ring or gasket size I need?
Seals are specified by inside diameter and cross-section thickness, not by the equipment they sit in. Measure the old seal, or use the part number from your equipment's parts diagram, since visually similar rings are frequently a size apart.
What is the part number for this seal?
Pro Series lists this seal under part number 4724. Quote 4724 when you cross-reference against your equipment manual, an existing part, or a parts diagram, so you are comparing the same revision.
Should I lubricate the seal on installation?
Yes - a thin film of silicone-based pool lubricant helps the seal seat evenly and makes the next service far easier. Do not use petroleum-based grease, which swells and degrades most elastomers used in pool equipment.
How do I confirm this fits my equipment?
Match the part number stamped on the component you are replacing, or look it up in the parts list for your Pro Series equipment. If your model or serial number is not named on this page, send it to us before you order and we will confirm the fit.
How often do pool seals need replacing?
Seals are consumables. Replace them whenever the component is opened, and sooner if you see flattening, cracking, a chalky surface or any weeping. A failed seal on the suction side draws air and can make a pump lose prime.
Is there a warranty on this seal?
It carries the standard Pro Series manufacturer warranty. The terms are set by Pro Series, and on some equipment the coverage only applies when a licensed professional performs the installation. Keep the receipt and packaging until you have confirmed correct operation.
