## Description

Product Description ...... 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: My Personal Opinion - This Canplas valve has worked excellently for me. While it’s true that it needs occasional cleaning, it’s a small price to pay to prevent a disaster inside my home. I recommend it to anyone who needs one for their own house—you won’t regret it.

## Questions & Answers

**Q: Can this be installed in a vertical position?**
A: I can tell you what happens when this is installed vertically, the lid cracks and sewage leaks all over the basement floor!  My plumber installed it vertically when my house was built 1.5 years ago.  It only took 2 guests staying in the basement for the lid to crack.

**Q: How long is the whole thing?**
A: Size 
6.5 x 6.75 x 9.75 inches

**Q: I have a drain in my backyard which i tie my drain into this sometimes backs up can this be used for this purpose.How much pressure to open it up ?**
A: I think it will work although there is no gasket, unless specs have changed since my installation! There could be some leakage. 
It takes very little pressure to open!

**Q: Is there a neoprene or other seal on the flapper to provide a positive seal?**
A: See http://www.canplasplumbing.com/plumbing.aspx?categoryID=385  -(put in whole http address)- and you will find their backwater valves and a replacement flapper. It is made out of ABS and has a neoprene ring just like the flapper in the valve.. The screw on top - access plug -also has a neoprene ring.
