Dual Check Valve Backflow Preventer


I have to install a Double check BF preventer. Now, my water line is against a wall and if I were to install the unit there I couldn't access the screws on the test ports.
Here is what I need to know... Can I install the unit upside down with the test ports facing the floor or should I just go ahead and start piping in a loop to put it in right side up and away from the wall?
It's a Watts 007 if that is important to know.

Just pipe it far enough out for service, replacement and adjustment make sure it's supported they are heavy.

LOL your name cracks me up.

Check other brands besides Watts. They are not all the same pattern. Some flow left to right, others right to left. This may help you.
As ColdIron said, support it well and make sure you have the proper room for servicing

I don't see a problem with the test cocks facing down...as long as it's high enough off the ground to gain access to them. I know the 007 can be mounted vertically as well.

If you really aren't sure, you can send Watts a note here:
http://www.watts.com/pages/support_email_form.asp

I have written to them before and they are pretty helpful (though it takes a day or two sometimes).

Do not install a Watts 007 upside down, it is not meant to function in that position, you can install it vertically, or in its normal position and work the piping around that. The checks in the valve do have springs, but if you install it upside down the springs are fighting against gravity and they will not seat properly.

Shows what I know!

If you mount it with the test ports screws in the back...wouldn't a right-angle flathead screwdriver do the trick to test?

Yeah, that should be fine, but I would try to maintain 6" of clear space behind it.

Don't mount it upside down.

The test cocks are threaded into the body of the DCVA. Just tighten them a half turn and they'll be in the right position (pointing out towards you). If you're scared about breaking them off, remove them, re-teflon and tighten them in to the desired position.

You probably shouldn't answer if you don't know what your talking about.

Tried to give a comment without being a wise guy.

I just gave the test cocks 1/2 turn as suggested and it went smoothly. It didn't feel like it was being over tightened, just nice. It was such an easy fix I feel foolish for not thinking of it. But, hey I learned something and I could pass it along if someone else finds themself in the same situation and then I could look like the genius! Thanks again for the idea!

Glad to hear it worked out for you!

I learned the same way, screwing around with a right-angle screwdriver against a wall and noticed a bit of teflon tape sticking out of the threads

Hello,
What are you installing the DCV on ? If you installed it on your main incoming water line to your house then you will need to install a expansion tank near your water heater for thermal expansion.Most codes require a RPZ back flow preventer if this is for a lawn sprinkler system.

I never said I knew for sure, and I directed him to ask Watts to double-check. Plus, someone else quickly corrected my mistake. That's the beauty of these forums.

Not sure what you meant by the "wise guy" comment.
