Using a WSSC licensed plumber is of paramount importance for several crucial reasons:
Compliance with Regulations: WSSC licenses signify that the plumber has met stringent regulatory requirements. Hiring a licensed plumber ensures that your plumbing work adheres to local codes and regulations, preventing legal complications and ensuring safety.
Expertise and Training: WSSC licensed plumbers undergo rigorous training and testing, demonstrating their competence in plumbing practices. Their expertise translates to efficient, effective, and professional plumbing services.
Quality Assurance: Licensed plumbers are committed to upholding high standards of workmanship. They use the best materials and industry-recommended techniques, guaranteeing the longevity and reliability of your plumbing systems.
Safety First: Plumbing work can involve complex systems and potentially hazardous materials. A licensed plumber has the knowledge and skills to prioritize safety, protecting you, your property, and the environment from potential risks.
Accountability: Licensed plumbers are accountable for their work. If any issues arise after the job is completed, you have recourse to address them through proper channels, ensuring your investment is protected.
Peace of Mind: Hiring a WSSC licensed plumber provides peace of mind. You can trust that your plumbing project will be handled professionally, with attention to detail, and in compliance with all necessary regulations.
Insurance Coverage: Licensed plumbers often carry insurance, offering further protection in case of accidents or unexpected damages during the project. This minimizes financial risks for both the homeowner and the plumber.
In summary, choosing a WSSC licensed plumber is not just a matter of compliance; it’s a guarantee of expertise, safety, quality, and accountability. It’s an investment in the long-term integrity of your plumbing systems and your peace of mind.
Is Len the Plumber considered pricey? It’s a valid question. Providing 24-hour same-day service comes with significant overhead costs. To offset these expenses, they may need to set prices that some people find on the higher side.

Hybrid water heater Takoma Park Md
Why Choose a Hybrid Water Heater for Your Takoma Park Home?
Hybrid water heaters—also called heat pump water heaters—blend cutting-edge heat pump technology with traditional electric water heating. Instead of generating heat directly, they extract warmth from the air around the unit and use that energy to heat your water. homeenergysavings.pepco.com
This process makes them significantly more energy efficient than standard electric or gas water heaters, resulting in:
Lower energy costs throughout the year
Reduced carbon footprint and eco-friendly operation
Consistent hot water delivery for daily use
Long-term savings that can offset the initial investment
Many homeowners in Montgomery County MD are now choosing hybrid systems to take advantage of rebates, tax incentives, and the long-term value these systems offer.
How Hybrid Water Heaters Work
A hybrid water heater combines two methods to heat your home’s water:
Heat pump technology pulls heat from surrounding air and transfers it into the water tank.
Electric heating elements act as a backup when hot water demand spikes or ambient temperatures drop.
By primarily relying on the heat pump, hybrid models can use up to two-thirds less energy than conventional electric systems—making them a highly efficient choice for homes in Takoma Park, Silver Spring, and beyond. Maryland Energy Administration
Benefits of Installing a Hybrid Water Heater

Adam spent the morning at our house testing our water heater. After many hours, including Kirk coming by to consult, they left without charging me at all! Adam is so friendly and helpful. I highly recommend Durance Plumbing!
Just completed our hot water heater replacement. The job was tough due to a tight space and older plumbing, but they cranked through and did a great job. Thanks!
LOOK NO FURTHER!!! This is the plumber to hire, if you want the job done correctly and for a great price! I called them after I was disappointed by the empty promises that I received from another company. I called and learned that this is a two-man show. I described the problem and felt very comfortable with the on-the-phone diagnosis. My partially clogged basement drain was snaked and opened. The cost was discussed over the phone and there were NO HIDDEN COST. Now, the icing on the cake, the plumber was neat, polite and extremely personable. Hire, them, you will be glad you did!

What Is WSSC Backflow Testing and Why Is It Required?
A backflow preventer is a mechanical valve assembly installed on your property’s water service line. Its job is to stop water from flowing backward — from your plumbing system back into WSSC’s public drinking water supply. Backflow can happen any time there is a sudden drop in water pressure: a water main break, a hydrant flush, heavy fire flow demand, or plumbing work nearby. When that pressure drop occurs, water from an irrigation system, boiler, fire suppression line, pool fill connection, or other auxiliary source can be siphoned back into the main — carrying contaminants with it.
WSSC Water (the Washington Suburban Sanitary Commission) requires annual testing of any backflow prevention assembly on a property where cross-contamination is a documented risk. The test confirms the device still seals correctly under pressure. Under WSSC regulations, the test must be performed by a certified tester and the results submitted electronically to the WSSC Cross-Connection Test Report (CCTR) database within 30 business days — by a registered Principal Master Plumber, not the property owner.

Frequently Asked Questions About WSSC Backflow Testing
How often does WSSC require backflow testing?
WSSC Water requires annual backflow preventer testing for all commercial properties and any residential property with a high-risk auxiliary system — including lawn irrigation, fire suppression, boilers, or pools. Results must be submitted to WSSC within 30 business days of the test date.
Can I submit my own WSSC Cross-Connection Test Report (CCTR)?
No. WSSC regulations prohibit property owners from self-submitting test results. The CCTR must be submitted electronically through the official WSSC database by a registered Principal Master Plumber within 30 business days. Durance is registered and handles all CCTR submissions directly on your behalf.
What happens if I miss my WSSC backflow test deadline?
Missing your annual WSSC backflow test deadline can result in non-compliance notices, fines, and in some cases water service interruption. WSSC typically sends a reminder letter, but the property owner is ultimately responsible for staying current. If you’ve already missed a deadline, call (301) 270-6663 — we can typically be on-site within 24–48 hours and restore compliance the same day.
What happens if my backflow preventer fails the WSSC test?
If the assembly fails, WSSC requires it to be repaired or replaced and then re-tested before a passing CCTR can be filed. Because Durance is a licensed Master Plumber — not just a tester — we can rebuild or replace the device and re-test in the same visit. We provide an itemized estimate before any repair work begins.
Do I need a backflow test for a residential property?
Most standard single-family homes on WSSC water service do not require backflow testing. Testing is required when a residence has an auxiliary system that creates cross-connection risk: a lawn irrigation system, fire suppression line, pool fill connection, boiler with chemical treatment, or similar. If you received a letter from WSSC, you need a test — call us and we’ll confirm what applies to your property.
How much does WSSC backflow testing cost?
Pricing depends on the assembly type, the number of devices on the property, and location. Most residential single-device tests are flat-rate. Commercial and multi-device properties receive a per-device quote. Call (301) 270-6663 for a same-day price specific to your address. All estimates are provided upfront — no surprises on the bill.
How long does a WSSC backflow test take?
A standard single-device test typically takes 30 to 60 minutes, depending on device size, condition, and site access. If a repair or replacement is needed, that adds time — but most failures are resolved in the same visit. We’ll give you a realistic time estimate when you call.
What is a WSSC CCTR and why does it matter?
CCTR stands for Cross-Connection Test Report. It is the official form WSSC requires to document a backflow preventer test result. It must be submitted electronically by a registered Principal Master Plumber within 30 business days of the test. A properly filed CCTR is your documented proof of compliance — without it, your property is non-compliant regardless of whether the physical test was performed.
Does Durance also handle DC Water and City of Rockville backflow testing?
Yes. In addition to WSSC jurisdiction, Durance is certified for DC Water backflow testing in the District of Columbia and for City of Rockville backflow compliance. Properties in Rockville city limits are on a separate water authority from WSSC — if you’re unsure which jurisdiction applies to you, call us and we’ll confirm in under a minute.
What types of commercial properties does Durance serve?
We serve the full range: retail and restaurants, medical and dental offices, multi-family residential buildings, HOA-managed properties, industrial facilities, and properties with irrigation systems, fire suppression lines, cooling towers, and boilers. We also work with property managers overseeing multi-site portfolios — handling bulk scheduling, proactive deadline tracking, and compliance documentation across multiple jurisdictions. See our commercial backflow compliance page for details.
What Our Customers Say
WSSC sent us a notice that our irrigation backflow preventer needed testing and we were already past the deadline. Durance came out the next morning, the valve actually failed, but they had the replacement on the truck. Installed it, tested it, and had the CCTR filed with WSSC before they left. One visit, one bill, back in compliance.
— Commercial property manager, Silver Spring
Called Kirk on a Wednesday about a WSSC backflow notice we’d been sitting on. He had us tested and registered by Friday. Same person on the phone, same person on the truck. Couldn’t be easier.
