## Description

Product Description Protects basements and other low level areas from the backflow of sanitary sewer, storm sewer, or septic system, positive seal created by neoprene O-Ring. From the Manufacturer This simple devices offers effective protection against the backflow of sewage and stormwater into homes and businesses. Under normal operation, the lightweight flapper opens and allows waste water to exit to sewer line. During a backflow,the flapper seals closed, stopping the flow from reaching interior drains entering the living space. Backwater valves (BWV)are recommended on all branch lines serving low level appliances, leaving the main line open to discharge and vent. Any drain openings behind the BWV are protected from backflows. A BWV can also be installed on the main line before it enters a building.

Review: Completely Confident - I feel so much more confident having this on the drain line from my kitchen. I live in a condominium complex and have neighbors upstairs. Our drain lines in the kitchen are connected so if they put grease or anything else that clogs up the line down their drain, the water backs up in my kitchen sink and dishwasher. I had been calling out the plumber 2x a year to clear the line to prevent it from effecting me before I found this product. I connected it to my drain lines myself. Product installed easily and installation is very straightforward. It's been 5 months and I haven't had any issues with drainage at all.
Review: Easy install and works great. - I like the ease of install and clean out. It’s gravity to close the inside door and opens with small amounts of water. This is not at your local hardware stores but should be. Great investment to protect a whirlpool tub of backup. Will probably buy again for the other bathroom remodel but since it’s not a whirlpool tub, really don’t need it.

## Questions & Answers

**Q: does not fit my 2 inch waste pipe?!**
A: Some 2 inch drain lines have very thin walls like for joints with soft plastic "wedge" seals (made to slide anywhere along the pipe) for the lines under the sinks by the traps.  I put this on 2 inch white PVC pipe (like for sprinklers) and it fit that.  Maybe that's the difference in the sizes you're having issues with (where it may fit the black drain pipes, but not those others).

**Q: Can this be installed on a verticle waste line from a washing machine?**
A: For this "check valve" to have the flapper swing down and "block" flow trying to return, the flapper MUST be set to swing DOWN.  Therefore it must have the big cap up with the line going horizontal (or could be mounted if flow it to go UP thru a pipe).  If you mount it so the line is up/down with it set so water flows down, the flapper inside will hang down (in the open position) all the time and allow returning water to come up (unless a surge of flow happens to slam it up).  So if you want this in such a line you can have a 3 foot vertical pipe for washing machine, do a 90 bend running water thru this horizontally, then continue down or thru a trap etc, but don't expect it to hold mounted vertically for down flow.

**Q: What is the part number for the replacement flapper for the 2-inch canplas backwater valve?**
A: Check their website

**Q: ¿Le sirve a una tubería de 2 1/2"?**
A: El producto llegó rápido, y me funcionó perfectamente.
