Backwater Valve Installation

Backwater(Backflow) Valve Installation

On days when the rain doesn’t want to stop, you’re likely to be consumed with the fear of experiencing a water backup problem in your basement. Cleaning filthy rainwater is bad enough, but having dirty sewage in your basement changes equations vastly. Imagine the smell of all things!

Thankfully, you can stop this by one simple thing: Introducing a backwater valve to your property.

What is a Backwater Valve?

A backwater valve is installed in a sewer line to allow extra water or sewage to have a unidirectional flow – out of the house. Whenever there’s a sudden downpour, the city’s sewer lines have to take much pressure, possibly resulting in the water or sewage having a back-flow towards the houses.

When you have a sewer system backup, i.e., a placed backwater valve, the sewage and rainwater won’t be able to make its way back to your property.

Some municipalities require personal and corporate properties to have backwater valves, and others highly recommend it. There’s a good thing about the installation factor of these valves – they can be done during the initial construction of the property, or retrofitted into prevailing ones. 

If there is a basement in your house, the hazards of water backup increase. It also happens if the street level is less than a foot under your ground floor.

Importance of Backwater Valves

You might neglect backwater valves because they’re not very talked about, but they can act as a first line of defense in your waterproofing strategy. Especially for older homes that can’t handle too many backwashes or flooding, these are of paramount importance. You have no control over the outside sewer system, but have power over your home’s resistance to flooding by installing a backwater valve.

Without a correctly installed and positioned backwater valve, sewage can easily sneak into your basement through sinks, toilets, tubs, and floor drains.

In multiple cities of North America, it’s obligatory to install backwater valves in new homes, and also offer monetary assistance to old home owners to upgrade their home’s waterproofing funnel. The city of Toronto follows this rule too, so why not consider placing a backwater valve that such important locations are concerned with?

Many people think installing a backwater valve might end up costing them a pretty penny, but it’s actually much less costly than they’d think. And not to mention the benefits overweigh the prices by a large range.

If you’re still questioning yourself whether you need a backwater valve or not, the answer is a definitive yes.

Installation during the construction of a new house is much cheaper than retrofitting one into an existing house.

How Does a Backwater Valve Work?

A sewer system directs sewage and surplus water out of the house. A backwater valve resists the same water or sewage from overflowing in your house in case on an overload in the main sewer line. Mostly, you can inquire the functionality of your valve by yourself by looking through the backwater valve access box’s clear cover. 

The small flap inside the valve is usually open, that allows the water to leave your premises. It also accommodates the ventilation of foul-smelling sewer gases. On either side of the flap, there’s a small floating device.

The floaters make the flap close on occasions where the water and sewage travels back, thus stopping the gunk from entering your house. Gravity will do its magic once the water retracts and the flap will back into the open position, ready to let out the water and sewage out of your house once more.

The process of installing a backwater valve starts by a skilled, licensed plumber creating a hole in the concrete floor, normally close to the floor drain. They will excavate all the way do to the main sewage line, shape out a part, and fix it with a brand new valve.

Like mentioned earlier, the clear top is a common feature of valves. This gives a view into whether he backwater valve is operating smoothly or not. There’s also a removable lid for cleaning purposes.

Without a correctly positioned and installed backwater valve, filthy sewage can make its way up to the basement via tubs, sinks, floor drains, and toilets.

Our water pipe busted in the downstairs bathroom. It was a total disaster. Our neighbor gave the number of Master Waterproofing. They came that day, looked at the pipe, gave us a rundown of how they would fix it. They started the work, and the next day, it was clean. They were professionals, alright. We were really satisfied.

Had my backup sewer valve installed by Master Waterproofing. They dug up my lawn, and when the work was done, they fixed my lawn back up. Their work was good, and now, I call them if there’s an emergency. My wife recommended them to her sister, and she loved their work as well.

Installed flow valves and some pump through Master Waterproofing, and they were amazing. Totally satisfied with their quality of work, the materials they used were of high quality. They respond quickly and finish their work on time. For plumbing emergencies, I now know who to call.

One side of our lawn used to get flooded every time it rained. It was unpleasant. A colleague of mine suggested Master Waterproofing. They came, checked it out, immediately got what needed to be done. They installed a new drainage system. They know their work very well, extremely good service and behavior.
