## Overview

The Threaded One-Way Swimming Pool Winterizing Valve (1.5 inch) by GIGIT INC is a durable, plastic check valve designed for 1.5-inch threaded fittings. It prevents water from re-entering return lines, enabling efficient winterization without draining your pool.

Compatible with in-ground and above-ground pools, this valve streamlines winter prep, saving time and water.

## Description

Winterize Without Having To Drain Your Pool This revolutionary pool valve has a unique one-way design to keep water from entering the return lines. There's no longer a need to partially or completely drain your pool to clear the water out of your pipes -- instead, replace your "eyeball" return fitting with this one-way valve, drain the water from the lines, fill them with antifreeze and rest assured that they won't refill with water and freeze over the winter. Compatible with the Aquador skimmer cover for winterization, this valve lets you blow out the return lines while it's installed. Featuring a durable, Buna-N O-ring, this winterization valve fits 1-1/2-in. threaded wall returns and pool cleaner fittings and won't deteriorate or move like rubber plugs. Great for in-ground and above-ground pools alike, this winter pool valve will save valuable time and water during your winterization process.

- For 1.5 inch threaded fittings
- One-way valve prevents water from entering the return lines

## Questions & Answers

**Q: Can this valve remain in place all year or do I have to remove it during pool season?**
A: These have a ball valve in them that allows water to flow in one direction only.  They can stay in place all season (without the rubber cap). The only drawback to this is that you will not be able to aim the flow of water like you would with the eyeball type fitting that usually goes on the returns.  I have these on my returns.  They are pricey but they work.

**Q: Do these simply srew into the threaded return lines?**
A: yes...the picture is deceiving.....that outer cover isn't included.

**Q: Does this come with the (cap wrench tool) that you use a 3/8" socket ratchet of your own to attach to the cap wrench to help install and remove?**
A: Thanks... the original one I bought many years ago provided the cap wrench... curious... Q: What do you use to install and remove this check valve if no cap wrench was provided?

**Q: What type of spray pattern do these valves emit when the pool pump is running?**
A: We use these for winterizing our pool
