The new version of the Overlock sewer backflow prevention system uses a single plunger instead of a pump.
It’s less expensive than the old system, which costs $3,400 to $5,000, but it also requires more care.
If you have a leaky sewer pipe or water main, the new system will stop it.
If it’s leaking in your home or office, you’ll want to get a water main inspection done.
For repairs like leaks in plumbing, the system works by releasing a hose and then using a water pressure regulator to pressure the water out.
The new system also features an electronic valve to make sure the water pressure is correct.
When you buy the OverLock system, you must have the current manufacturer’s label on it.
A new version will be available in 2019.
