Re: Backflow Preventers on Potty Pump Out Dock
After reviewing your pump-out operation's and the pictures of the system,I realized that
_ the use of both a drinking,water hose and a sewage tank flushing hose on the same faucet
without a backflow preventer is an immediate public health hazard:
You are hereby notified that you must immediately install hose bib backflow preventers
at all hose connections on the dock where pump-out operations are taking place.Thea,
alternative is to disconnect the water supply to this dock.
Ace hardware has 6 hose bib backflow preventers which are IAPMO and ASSE approved
devices. Menards said they had two devices,but they were not sure if they were
approved.These are not the self draining type which are preferred in northern climates
for freeze protection but will work as backflow preventors and can be blown out in the
winter.
If the backflow preventers are not installed by noon on Friday June 7,2002 the City will
request that you disconnect the dock from the water system. If this is not accomplished,
we will shut off water at the City connection to the water supply system.
If you have any questions you can contact me on my digital pager at 651-642-7213.
