Your plumber is required to install a system which comes to the ground level and provides easy access for cleanup and, potentially, repair.

Before installing a backwater valve,  ask a certified licensed plumber to inspect the drain system of your house and find the best place for it. Installation location impacts its ability to prevent sewer backup, and your ability to maintain the device.

Taras from High Park:"We have a tenant in our basement appartment and have previously done extensive work with other drain companies. I called one of the companies up and they wanted too much for just coming out and inspecting. I remembered Dmitry because he did a few other plumbing jobs for me very well. I was pleased to hear that he also does camera inspections. Dmitry removed the toilet and pulled out a mass of roots the size of a 20 pound salmon! Dmitry did the camera inspection which revealed that the pipes were absolutely clean and clear of all roots. So where did the roots come from?..."

As a rule, a backwater valve  has to be installed either on main sewer pipe or the basement branch line  to protect all the  fixtures located below grade. Sometimes, the perfect location is hard to access. Other times, locating that place from the first time is difficult, and a plumber needs to jack-hammer more basement floor than originally intended.

Some plumbing companies, ours included,  also get a building permit on your behalf, saving you a trip to the City Hall. Then they help you fill out an application and schedule city inspectors.

Main advantage of an indoor install is that backwater valve is easily accessible. It is protected from the weather elements. You can visually inspect it, or, in case of spillage, literally smell the malfunction. Indoor install is easier and, therefore, costs you less than outdoor one.

Another disadvantage is cost, which is a bit higher than the cost of an indoor install. However, comparing to the cost of potential basement renovation, or backwater valve’s esthetic impact on the looks of your basement,  this extra cost may become an advantage.

Note that in the cold climates, burying the device  deep in the ground is a good thing.  Freezing temperatures won’t  impact your backwater valve too badly.  However, if you own a bungalow with a crawl space in  Manitoba, your plumber may recommend to avoid an outdoor install. This is because your pipes are closer to the ground, and it’s really cold in Manitoba for extended periods of time.
