WATTS Backflow Preventer leaking

Hi,

I should start off by saying I'm a very amateur DIY'er, but not afraid to roll up my sleeves and attempt DIY jobs.

I have a Weil Mclain wtgo-4, oil fired boiler, with a 1/2 9D-M3 WATTS backflow preventer installed. A few months ago, I noticed a few gallons of water on the floor under the discharge pipe connected to the backflow preventer. I have since placed a 5 gallon bucket under the pipe and am emptying the bucket once every couple of weeks (about 3-4 gallons a trip).

Should I replace the backflow preventer, which I've found at Home Depot for about $45, or is this a sign of a bigger issue and the backflow preventer is performing as intended?

Thank you
Trevor

It's probably just the backflow preventer leaking... it's very easy to change out... you have valves on both sides to facilitate.

See also this thread, scroll down to the diagrams I posted of how they work for more reassurance that the problem is with the valve and not the system.
