Cross-Connection Control Is An Essential Component of Safe Drinking Water Systems
Plumbing system cross connections, which have been defined as existing or potential connections between potable, safe to drink, and non-potable water supplies and continues to be a serious potential public health hazard.

Waterborne disease outbreaks have been controlled, but not yet eliminated. Properly installed and maintained backflow prevention devices are critical elements of safe drinking water systems in our communities and workplaces.

The cross-connection problem is an ongoing dynamic one, because potable water piping systems are continually being installed and altered, while water using devices and equipment which can contaminate a drinking water system often are connected to potable waterlines without appropriate, properly installed backflow preventer valves.

Certified for Cross Connection Control
Check your home for cross connections is very important: If the fill valve in your toilet is not at least 1″ above the overflow tube you can siphon water from the toilet tank into your drinking water. If you have an unused water softener still hooked up you can get stagnant water into your drinking water. If you do not have a vacuum breaker on your hose bibs you can get dangerous chemicals back syphoning into your drinking water through your garden hose. See our checklist below.

Cross Connection Check List

  1. Do you have an old water softener which is connected and not in use anymore?
  2. Is your toilet water fill valve at least 1 inch above the overflow tube?
  3. Do you have a vacuum breaker on the hose bibs?
  4. If you can connect a garden hose to your laundry faucet, does it have a vacuum breaker?
  5. Does your sprinkler system have a PVC, SVB or RPZ backflow preventor?
  6. If you have a PVC, SVB or RPZ backflow preventer, has it been tested within 2 years?
  7. Does your boiler supply have a dual check valve?

If you answer “Yes” to question 1 or “No” to any of the questions 2 – 7
you should call and schedule a repair appointment as soon as possible.
