backflow preventer?
Someone mentioned it's a good idea to install a backflow preventer on the
house sewage line. I searched google for such product and found a few different ones of different shapes and prices, some are called backwater preventer, some called flood guard. I still have no idea which is the correct type. Could someone point me to the correct type to use for a family house? I have access to the sewage drain pipe (4-inch black plastic pipe) in the crawlspace and would like to install myself if it's just a matter of cutting the pipe and inserting the device. |

It can be confusing. A backflow preventer is used on a potable water service (city supply). A back WATER valve is the one used on a sewer lateral to prevent the city sewer from backing up into a house. If you have access to the Main drain, you have it made! The latest PVC and ABS Backwater valves are slick indeed. See: http://www.superiorspecialty.com/Mai...rmoplastic.htm http://www.dafehr.com/Canplas/cisbwvalve.htm http://www.websitement-tm.com/z_webs...ter-Valves.htm Not needed in your crawl space, but this design features an extension to the ground surface, where the Main drain is buried, which allows the flapper to be pulled up for cleaning/repair/inspection without doing any digging! http://www.cleancheck.com/about.htm Jim |

Yea, the correct term is Back Water Valve. It is a defense against sewer flow from your municipal sewer system. It allows sewage to normally flow from your building, but in the event of stoppage in the municipal system and sewage flow is directed towards your property a “flapper” inside this valve body will close. When the normal sewer flow resumes the “flapper” will return to its normal position.
