Non-Potable Water Applications
Product Highlights
Description
BBFP Dual Check Valves with Intermediate Atmospheric Vent prevent the reverse flow of hot or cold polluted water from entering into the potable water supply.
It consists of a brass body with stainless steel internal parts, integral strainer, and two durable, tight-sealing, rubber check valves.
Designed for continuous pressure, non-health hazard applications in smaller supply lines, such as laboratory equipment, processing tanks, sterilizers, dairy equipment, and specifically for boiler feed lines.

If it is dripping from the center hole one of the check valves are leaking. It would need to be taken apart and cleaned or replaced. Good luck, John
Q: I have an RV Lot with four to six campers. Do I need 4 to 6 separate Preventers or will one be fine on the main line where it branches to the different trailers.
Asked by deak 11 years ago
Add your answer
You need one for each camper in my opinion. If something goes wrong in any one camper and you get backflow, you can contaminate water supply to other campers.
The correct way is one for one. Each hose should have its own Sent from my Android powered by Cellcom 4G LTE
These are NOT to be used for potable water! They do not meet NSF requirements!

Yes it will
I used this valve to replace a 9D-M3.
Q: Can this valve be used to let fresh water from the house to keep the hydronic system water full,without contaminating the fresh water?
Asked by monty 12 years ago
Add your answer
The purpose of the valve is to keep fresh water from being contaminated by other water such as boiler water so your application is exactly the way the valve should be used.
Yes it can, as one would need a backflow on a closed system.
Yes it can.
Yes, that is exactly what you used it for, to prevent back flow from your system going back into your fresh water supply
Q: Can this be used with water powered sump pump?
Asked by Chaz 12 years ago
Add your answer
I believe so, but do not know for certain. Ron
I don't see any reason why not. As long as there is nothing but fresh water in the flow, no trash. Hope that helps.
I used mine for a heating system so I don’t get backflow from the heating system into the water supply. I see no reason why you can’t use it for a sump system.
Yes you can. It operates on the same principle as with a boiler - preventing contaminated water from entering your water supply. However, you should consider using a 3/4 inch supply because the 1/2 inch supply may not provide enough vacuum to lift the water from the sump well.
Q: Does the backflow preventer have to be installed horizontaly or can it be installed vertically ?
Asked by none 14 years ago
Add your answer
You can install it in either configuration, if vertical, be sure flow is downward. Walter
Either way, it states it right in the directions
No does not matter Matt Caward
It will work fine if you are zoning and have a circulator to move the water
