Hey everyone – Welcome to this week’s episode of “How NOT to Call the Plumber”!
Unfortunately, storms like the one we saw last week are becoming more and more of a regular occurrence. We’ve watched as what used to be called a “once in a generation” storm has moved to “once in a decade” to “once every few years”. The constant change of global weather patterns will only make these storms more common, which is why you need to take the necessary steps to protect your home. These steps aren’t considered “extra layers of protection” anymore, but rather absolutely necessary in order to stop basement flooding.
You may have heard us talk about this before, but we're writing about this again because we’ve heard too many homeowners over the years call with the regret of not spending just a few hundred dollars in a sump pump replacement just to have their basement flood to the tune of a $50,000 renovation (which is often not covered by insurance in today’s home insurance policies).
The two most important pieces of equipment that you can have in your basement are Sump Pumps with Battery Backup Systems to protect against naturally-occurring water (rising groundwater and rainwater from exterior drains) and Backwater Valves to protect from sewage backing up from the City sewers into your basement.
The City of Toronto knows the importance of these pieces of equipment, but also knows that they can be expensive to install. That’s why they offer rebates through the City of Toronto Basement Flooding Subsidy to help cover the cost. Believe it or not, these rebates are large enough that they often cover a substantial amount of the installation costs, many times up to 80%.
For some context, if you have an existing sump pump that you are looking to replace and add a battery backup system, the out-of-pocket cost after the city rebate is likely to be less than $300 – yes, you read that right! Backwater valves can be slightly higher after the rebate, ranging from about $3,000 to $7,000.
We don’t often directly plug our business, but If you have any questions or are interested in taking advantage of these rebates, please feel free to reach out. At Watermark Plumbing and Drains we help hundreds of customers every year with installations just like these, and we're very proud to say we have over 1,000 five-star Google reviews to show you’d be in very good hands!
