Protect your property from what you can’t see coming.

When it comes to storm protection, most people think about wind and water from above—but few realize how easily water can rise from below. The Clean Check™ Backwater Valve System is designed to prevent unwanted sewage and stormwater from backing up into your home or building through the plumbing system.

At Diamane Architecture Design & Construction, we offer professional installation of these critical valves as part of our comprehensive hurricane and flood preparedness services—giving you one more line of defense where it matters most.

What Is a Backwater Valve?

A backwater valve is a one-way plumbing device that allows water and waste to flow out of your home or business—but automatically closes to block water from flowing back in during heavy rainfall, rising floodwaters, or sewer backups.

The Clean Check™ valve is one of the most trusted and durable systems on the market, designed for easy access and long-term protection.

Key Features:

  • One-way valve prevents sewage or stormwater backup

  • Installed underground by a licensed plumber

  • Easy-access design for future maintenance

  • Compatible with new builds or retrofits

  • Required or recommended in many flood zones

Hurricane & Flood Protection

Hurricane & Flood Protection

Storm surge and extreme rainfall put enormous pressure on municipal systems—and when those systems fail, your home becomes the release point.

We’ve seen the impact of sewer backups on beautifully finished homes and commercial spaces. The damage is messy, costly, and preventable. The Clean Check™ valve is a simple yet powerful way to protect your property, your peace of mind, and the integrity of everything you've built.

It’s not the flashiest upgrade—but it might be the most important one you make.

Who Should Install One?

We strongly recommend a Clean Check™ system if your home or building has:

  • A basement or lower-level floor drains

  • Plumbing fixtures below street level

  • A history of sewer backup or localized flooding

  • Location in a floodplain or coastal zone

  • A desire to protect recent or planned renovations

It’s especially critical for properties like:

  • Single-family homes

  • Multi-family and apartment buildings

  • Restaurants, daycares, and small businesses

  • Healthcare facilities and nursing homes

  • Schools and public-use buildings
