Watts LFRK909M1-CK1 1 1/4-1 1/2 – Frequently Asked Questions
1) Which Watts backflow preventers does the LFRK909M1-CK1 first check repair kit fit?
The LFRK909M1-CK1 kit services Watts 909M1 and LF909M1 reduced pressure zone assemblies in sizes 1-1/4 inch through 2 inch. The specific kit designation covers the 1-1/4 and 1-1/2 inch bodies. If your assembly is a plain 909 (not the M1 version), this is not the matching kit.
2) What parts come in the Watts LFRK909M1-CK1 first check kit?
You get the disc assembly, spring, seat, seat O-ring, cover O-ring and lubricant. That is everything needed to rebuild the first check module itself. The kit does not include second check or relief valve parts, so if the test shows the relief valve or second check failing you need those kits separately.
3) My RPZ is failing its annual test and dripping from the relief port. Is the first check kit the right fix?
Continuous relief discharge on an RPZ usually points at a fouled or worn first check, and the first check rebuild kit for the 909M1 and LF909M1 is the part that addresses it. The kit supplies the disc assembly, spring, seat and both O-rings so the check reseats cleanly. If your test gauge shows the relief valve opening point is out of range rather than the check leaking by, you need the relief valve kit instead.
4) Will the LFRK909M1-CK1 1 1/4-1 1/2 kit work on a 2 inch 909M1?
The RK-LF909 family covers 1-1/4 inch through 2 inch assemblies, but the check kits are split by size band. This one is the 1-1/4 to 1-1/2 inch kit. For a 2 inch 909M1 or LF909M1 you need the 2 inch first check kit in the same series, not this part.
5) Is this Watts repair kit lead free for potable water service?
Yes, the RK-LF909 series first check kit is a lead free kit, which is what you want when rebuilding an LF909M1 on a potable water line. Rebuilding a lead free assembly with non-lead-free wetted parts defeats the reason the LF body was specified in the first place.
6) What Watts part number should I order for this first check kit?
Order by MPN LFRK909M1-CK1 1 1/4-1 1/2. Watts also catalogs it under part number 794063, in the RK-LF909 repair kit series. Quoting the MPN with the size band is the safest way to avoid getting the wrong check or the wrong size band.
7) Do I need to buy lubricant separately when rebuilding a 909M1 first check?
No. Lubricant is packed in the kit along with the disc assembly, spring, seat, seat O-ring and cover O-ring, so the O-rings can be dressed during reassembly without sourcing anything extra.
