The Atmospheric Vacuum Breaker (AVB) Type Backflow Preventer

As town and city water departments are becoming more concerned about the potential for contamination of potable water supplies, Backflow Prevention is becoming a hot topic of discussion in many municipalities across North America. As a result, if your local water/plumbing department does not currently insist on 'approved' backflow prevention devices being fitted to components that you install in your domestic water system, they probably will soon.

In order to address this issue positively, we have introduced the Basementsaver WPA and HPA water powered backup sump pumps with 'approved' AVB backflow prevention devices. The Atmospheric Vacuum Breaker (AVB) is one of the simplest, most cost-effective, and most reliable 'approved' backflow prevention devices available, but it must be installed and used correctly.

The AVB functions by allowing atmospheric air to enter the water system whenever there is potential for the siphon effect to initiate. Under normal conditions a poppet valve inside the AVB is forced to remain closed by the system water pressure. However, if the water pressure in the upstream side reduces below atmospheric pressure, the poppet valve opens to the atmosphere so that air enters the system and prevents siphon formation.

General AVB Backflow Preventer Use Guidelines

An AVB should never be subjected to continuous full system water pressure - which could cause the poppet valve to malfunction by locking in the closed position. For this reason, an AVB should always be installed downstream of a shut-off valve and never be installed upstream of a shutoff valve.

Additionally, in order to prevent continuous nuisance leakage, the AVB should always be installed above the highest point of the downstream route to discharge (ie. slope the discharge downwards to facilitate drainage).

Things You Need To Know About 'Approved' Backflow Prevention

Tim Harnois
Master Plumber & Owner of +Aquamedic

'Approved' AVB Backflow Protection May Not Be Enough!
An AVB is an 'approved' non-testable backflow prevention device. In my experience these simple and inexpensive devices perform both reliably and effectively, with essentially zero maintenance needs, when installed correctly. However, AVBs are not listed as 'testable' backflow prevention devices.

Some Plumbing Inspectors may specify that you install a 'testable' backflow prevention device! In this case you may install an upstream Spill-Resistant Vacuum Breaker (SRVB) backflow preventer - Avoid an RPZ device, which may prevent the pumps working correctly! SRVB units are readily available, but they are relatively expensive and they have to be tested by a Certified Backflow Prevention Device Tester at installation, and then re-tested, usually every year, thereafter - this can become too inconvenient and expensive for most peoples tastes!

My Philosophy!
If you do consult your plumbing inspector, and he insists that you need an SRVB device, Your best option in most cases is to forget about a water powered backup sump pump and go with a Basementsaver BP Battery Backup Pump instead!
