Backwater Valve Maintenance

It Only Protects You If It’s Working.

A backwater valve is one of the smartest ways to protect your basement from a sewage backup.
But like anything mechanical, it needs attention to keep doing its job.

We’ve seen what happens when it’s ignored — stuck flaps, clogged chambers, debris buildup that turns a once-safe system into a useless one.

So at UPR, we don’t just install backwater valves.
We keep them working.

 Why Maintenance Matters

Backwater valves are simple — and that’s part of their strength.
But over time, grease, debris, scale, and even wipes can collect in the chamber or jam the float system.

When that happens, the valve may:

  • Stay open when it should shut

  • Fail to close fully

  • Trap sewer gases inside your home

  • Or worst of all — not close at all during a backup

And the moment you need it most? It fails.

Regular maintenance keeps the mechanism clean, the flaps responsive, and your protection solid.

 What We Do During Maintenance

At UPR, we offer professional, non-invasive valve servicing designed to extend the life and reliability of your system.

Every maintenance visit includes:

  • Visual inspection of valve chamber and components

  • Cleaning of internal flaps, seals, and floats

  • Lubrication (if required)

  • Debris removal

  • Testing for smooth, responsive operation

  • A professional report and service record for your files

We also check for wear and tear, signs of corrosion, or issues caused by improper installation — and we fix them before they cause damage.

How Often Should You Service It?

The City of Toronto recommends inspecting and cleaning your backwater valve at least once per year, or more often if:

  • You’ve had a recent backup

  • You notice sewer smells

  • Your home has high wastewater use

  • You live in a high-risk flood zone

And if your valve was installed through a rebate program, regular maintenance may even be a condition of coverage.

Signs Your Valve May Need Attention

You don’t need to wait for a flood to know something’s off.
Watch for:

  • Gurgling drains or slow flow

  • Sewer odor near the valve

  • Water pooling in the access pit

  • No record of recent inspection

  • Flap looks jammed or stuck open when checked

If you’re not sure how your valve is doing — let us take a look.
