Product details

The Val-Pak V20-339 is a spa return check valve eyeball with a standard 1-1/2 in. male thread. It replaces the plain return eyeball in an overflow spa and adds a one way valve behind it.

The problem it solves

In a spa that spills over into the pool, the spa sits higher than the pool. When the pump stops, water in the spa wants to run back out through the return plumbing and into the pool. A check valve in the return holds it where it belongs.

Fitting it

The valve is contained in the eyeball, so nothing has to be cut into the pipework. It threads into the existing 1-1/2 in. return fitting in place of the eyeball that is there now.

If your spa is losing level to the height of the return and no further, this fitting is the first thing to check.

Questions and answers

What people ask about this product, answered by our pool techs.

What does this fitting actually do?
It is a return eyeball with a check valve built in. Water flows into the spa while the pump runs, and the valve closes when the pump stops so the spa does not drain back through the return line.
What size is it?
It uses a standard 1-1/2 in. male thread, so it goes into a standard 1-1/2 in. threaded return fitting.
My spillover spa loses water overnight. Is this the part?
If the level drops to the return line and stops there, a failed or missing return check valve is the common cause. Suction side plumbing and the spillover itself are the other places to look.
Is this a Val-Pak part?
Yes. It is Val-Pak V20-339.
