I follow the mfr instructions for maintaining the 825's. Water will remain in the relief assembly and in the second check valve. Dissassembly is the one certain way to get every last drop of water out. Besides, it is a chance to find a sticky poppet. And they do get sticky over time.

If it was a double check it wouldn't be leaking

For that matter, we have the same policy with the double check Watts 709 DC-140.
The replacements parts are extremely expensive, as well as the checks are hard to gain access too. We usually just replace them with a new assembly.

Though we do offer the chance to repair them if they like

Wet Boots - Are you winterizing these systems with compressed air then? Just blow thru the device & exercise both ball valves and all 4 test cocks. We do not disassemble them unless there is a problem.

You will not free up sticky poppets with an air compressor. And you will not completely empty the relief section. Look at a Conbraco RPZ, with upward-oriented check valves and a testcock on the relief assembly. That's what the 825 would need to not have any water remaining.

Also, I do some last-minute winterizings with a truck-mounted dinky compressor, and I wouldn't even try blowing through an 825 with the little wheezer.

We blow thru 1,000 every fall and do not have to unstick many if any RV poppets in spring.

I reckon we are lucky.

Since no one was testing the Febco devices, stuck poppets weren't obvious to me until I had a broken DCVA that was physically cracked from internal forces and a stuck poppet. Since then, it becomes an inconvenience to follow mfr instructions on the 825's, but it does allow me to observe when the internal parts begin to bind.

There's the difference - Our devices are almost all tested annually.

I'm not sure the broken DCVA would have tested bad the year prior to its destructive failure. No problems with seats or discs. Just the poppet binding in its guide.

I expect water quality (hardness) could play a role in the Febco failures.

Remove POS Watts and install a quality Febco 825Y or a Wilkins 975XL......

That is SOP for me and my guys, they are not worth the time to try to repair...

I guess the real question is what is involved in the repairs. Myself, I don't trust a body casting once there's been a freeze. Could be the 009 has a replaceable relief-valve seat that can crack.
