Service Overview
Backwater Valve Installation Backed by 65+ Years of Local Experience
When the municipal sewer main surges, backs up, or becomes blocked, the pressure has to go somewhere — and without protection, it flows directly into your home through floor drains, toilets, and lower-level fixtures. The result can be thousands of dollars in damage, lost belongings, and a major health hazard.
A backwater valve — also called a backflow preventer — installs on your main drain line and acts as a one-way gate: wastewater flows out, but nothing flows back in. Lapin Services has protected Central Florida homes and businesses since 1958, and backwater valve installation is one of the most reliable ways to prevent one of the most destructive plumbing emergencies homeowners face.
Problems We Solve
Common Backwater Valve Installation Problems We Fix
Here are the issues our team commonly finds and resolves during backwater valve installation calls across Central Florida.
Sewer Main Surges and Overflows
Heavy rainfall or high demand can overwhelm the municipal sewer main, sending sewage pressure back through connected drain lines and into unprotected homes at ground level or below.
Sewage Backing Up Through Floor Drains
Floor drains in garages, laundry rooms, and lower-level bathrooms are common entry points for sewage backup — often the first sign of a surging or blocked sewer main.
Sewage Entering Finished Living Spaces
Once sewage enters a finished area, the damage extends beyond cleanup — flooring, drywall, personal property, and HVAC systems can all be affected, driving remediation costs into the tens of thousands.
Repeated Backup Events
Homes that have experienced sewage backup more than once are at high risk of recurrence, especially in areas where aging sewer infrastructure struggles to handle peak flow.
No Existing Protection on Older Homes
Many homes built before modern plumbing codes were adopted were never equipped with backflow prevention on the main drain line, leaving them fully exposed to sewer surges.
When to Call
Signs Your Sewer Connection Needs Professional Attention
If you notice any of these warning signs, schedule backwater valve installation before the problem becomes more disruptive or expensive.
You've Had Sewage Back Up Into Your Home Before
If raw sewage has ever entered your home through a drain, toilet, or floor drain, a backwater valve is one of the most effective ways to ensure it doesn't happen again.
Your Home Has a Basement or Ground-Level Drain
Lower-level spaces and ground-floor drains are the most vulnerable to sewage backup. Any home with these features should have backflow protection on the main drain line.
You're in a Flood-Prone or Low-Lying Area
Homes in areas that experience frequent heavy rainfall or have historically dealt with drainage issues are at elevated risk of sewer surges during storm events.
Your Neighborhood Has Aging Sewer Infrastructure
Older sewer mains are more prone to blockages, capacity issues, and surges. If your street or neighborhood has a history of sewer problems, your home needs protection.
You're Renovating or Adding a Bathroom Below Grade
Any time you add or renovate a bathroom or drain fixture at or below grade, it's the right moment to install a backwater valve as part of the plumbing work.

FAQs
Backwater Valve Installation FAQs
What is a backwater valve and how does it work?
A backwater valve is a one-way gate installed on your main drain line. It allows wastewater to flow out of your home normally but automatically closes if sewage attempts to flow back in from the municipal sewer system during a surge or blockage.
Where is a backwater valve installed?
It’s installed on the main drain line, typically where it exits the foundation of the home and connects to the sewer lateral. The exact location depends on your home’s plumbing layout, which our technician will assess during the visit.
How long does backwater valve installation take?
Most installations are completed in a single visit, typically within a few hours. The timeline can vary depending on the accessibility of the drain line and whether any excavation is required.
Will I need a permit for this installation?
Permit requirements vary by municipality. Lapin Services handles all permitting and compliance requirements when required, so you don’t have to navigate that process on your own.
Does a backwater valve require maintenance?
Yes. Backwater valves should be inspected and cleaned periodically — typically once a year — to ensure the flap mechanism moves freely and is free of debris. We can show you how to do a basic check or handle maintenance visits for you.
Can a backwater valve cause any plumbing problems?
A properly installed and maintained backwater valve should not affect normal drainage. If a valve becomes stuck closed due to debris buildup, drains can back up — which is why routine inspection is important. Our installations are designed with accessibility in mind.
Is a backwater valve the same as a check valve?
The terms are sometimes used interchangeably in residential plumbing, but backwater valves are specifically designed for sewer line protection and built to handle the volume and conditions of a sewer backup. We install the right type of valve for your application.
Do you serve areas outside Orlando?
Yes. Lapin Services serves all of Central Florida. Call (407) 326-3367 to confirm service in your area and schedule an appointment.
