## Overview

## Description

This 3/4" water check valve is installed in the inlet side of the circulation pumps plumbing to prevent the back flow of water through the circulation pump once the jet pump is activated. All water check valves have arrows stamped on the outside to indicate the direction of flow which should be pointer towards the circulation pump. These low flow water check valves come in two sizes (1/2" #HTCP70173 & this 3/4"). This is for a Single Watkins Water Check Valve, 3/4" OEM Replacement High Grade Quality that's made to last!! Troubling Shooting: The symptoms of a non-operative check valve are; * Water Leak - If water is leaking from around the check valve, it should be replaced. * Rattling - A rattling check valve indicates that water is not being allowed to flow properly past/ through the check valve. * Verify the check valve is installed with the flow in the correct direction. * Heater High-Limit Tripping - Poor water flow through the check valve could lead to heater high-limit tripping. Ensure the check valve is not block by debris and operating properly. * Surging jet pump (on spas equipped with a flow switch).

Review: Great for your dishwasher! 😁 - Like another reviewer, I too was looking for a better back-flow solution for my dishwasher and found this! Dishwashers need a check valve to keep water from the garbage disposal from flowing backwards through the drain hose into the dishwasher. And the check valves sold for dishwashers are usually a very cheap rubber flap or “duck bill” type valve. They don’t work well, fail often, and generally suck. This is a very well made, solid, yet simple check valve. It works perfectly. It’s super rugged and will probably last longer than the dishwasher itself. I don’t understand how some reviewers can claim it leaks, etc. You can simply blow into it to see how well it seals (which is very well!). Maybe they installed it backwards? Anyway. If it will work for my little dishwasher pump, it will surely work in your hot tub! My hot tub doesn’t use check valves anywhere, or I would certainly use this one.
Review: Works perfectly! - This item works perfectly in my Watkins Classic. We'll see how long it lasts...

### ⭐⭐⭐⭐ It did leak
*by S***W on June 12, 2021*

I used this on a dishwasher drain to disposal. It leaked right out of the package, put water an pressure on the stop side, and it did drip, quit heavily actually. This might be acceptable for a spa, but stagnate water in the dishwasher isn't. Put Dielectric gel on the plunger an seat, problem solved. Vaseline would work as well. Happy with the product for using what it wasn't designed for.
