Protecting your sprinkler system: The importance of proper blowout connection placement
As we approach the colder months, many homeowners are preparing their sprinkler systems for winter. One crucial step in this process is the sprinkler blowout, which removes water from the lines to prevent freezing and damage. However, a common installation mistake can turn this preventative measure into a costly problem. Let’s dive into why the placement of your sprinkler blowout connection matters and how it can save you money and headaches.
The Problem: Misplaced blowout connections
Many sprinkler systems have their blowout connection installed before the backflow prevention device. This seemingly minor detail can lead to significant issues. When an air compressor is used to blow out the sprinkler lines, it can subject the backflow device to excessive air pressure that it’s not designed to handle. The result? Potential damage to your backflow device, leading to expensive repairs or replacements.
The Solution: Proper placement is key
The fix for this problem is straightforward but crucial: install the blow-off connection for the sprinkler system on the house side of the backflow device. This simple adjustment in placement offers multiple benefits:
- Protects the backflow device: By positioning the blowout connection after the backflow device, you shield it from the high-pressure air used during the blowout process.
- Maintains system integrity: This placement allows the backflow device to perform its primary function – preventing forced air pressure from entering back into the water distribution system.
- Prevents water supply issues: Keeping air out of your home’s water distribution system helps avoid potential “water events” caused by air in the pipes, which can lead to sputtering faucets or even damage to plumbing fixtures.
The win-win scenario
Proper installation of the blowout connection creates a win-win situation for everyone involved:
- For homeowners: You avoid the unnecessary expense of repairing or replacing damaged backflow devices. Plus, you reduce the risk of water supply issues in your home.
- For the community: By preventing air from entering the water distribution system, we maintain the quality and safety of our shared water resources.
