Spring sprinkler start-up in Takoma Park is the time to test your backflow preventer. We handle testing, fix failed assemblies, and replace freeze-damaged units.
Your backflow preventer may need work if
- Valves or test cocks are corroded or seized
- It hasn't been tested this year
- Water spraying or dripping from the relief valve or bonnet
- Freeze damage after winter (cracked body or popped bonnet)
- Low sprinkler pressure after start-up
- Your water utility sent a testing notice
Why testing is required
In WSSC Water's service area, residential irrigation backflow preventers must be field-tested every year at spring start-up, and only WSSC-licensed plumbers who are also certified cross-connection technicians can test or repair them. Results must be reported to the utility. Customers of other water systems (such as City of Rockville or Town of Poolesville water) follow their own cross-connection rules.
Takoma Park homes: what we see
Older Takoma Park properties that added irrigation later sometimes have backflow devices installed in tight or non-compliant spots. We check height and location requirements during testing.
Most Takoma Park homes are on WSSC Water, which licenses plumbers in its service area and runs the cross-connection (backflow) program.
What we test
Most residential systems use a pressure vacuum breaker (PVB) or a double check valve assembly. We check that each check valve holds and the air inlet opens properly, record the readings, and handle the paperwork. If it fails, we'll tell you exactly which part and what the repair costs.
Winterizing to prevent damage
Many failures we see in spring are freeze damage. Before the first hard freeze, shut off the irrigation supply, open the test cocks slightly, and have the system blown out. A cracked backflow body means replacement, which costs more than prevention.

Seasonal tips
In spring, open the supply valve slowly to avoid water hammer. In fall, close it, open the test cocks a quarter turn, and have the lines blown out. Don't adjust internal parts — testing and repair must be done by a certified tester.
