Swift Check w Old Style Red Jacket

[hahutt]

Hey, pulled up on a site today with old style red jacket and a plld with no swift check. Site was having issues with jumping cents. Put gauge on line and it drained all the way to 0 psi in about 10 minutes. Looks like it has a new functional element and the line seats at 11-12 psi. My question is are all old style red jackets required to have a swift check with plld?

P.S. Also didn’t check ATG, thought about it as I was pulling off to the next job. I glanced at it and just saw one alarm for low level but no plld alarms.

No, I don’t believe it is required for the old style red jackets to have a swiftcheck valve. Just make sure it has this part number according to Veeder-Root (848480-001). I have 3 Older red jackets with PLLD and no swift right now.

With that being said, I would say your issue (meter jump or jumping cents) would most likely be with the packer o-ring, meter check valve, or check valve relief pressure is too low. Check the packer o-ring by separating the STP housing and it’s located below the PLLD. Also check the o-rings on the functional element. They are cheap easy fixes most of the time. While you are in the STP sump, go ahead and turn up the pressure on the functional element. If that doesn’t correct the issue, check the meter check valves.

I was always taught that red jacket had to have swift checks and fe petro did not.

I agree with Kperlow. I always thought the old style RJ used a swiftcheck and a gutted Functional Element, and the FE Petro used a precision check valve with the "R" stamped on it and no swift check.

In the Veeder Root Line leak application guide(577013-465) it lists the swiftcheck as the first check valve used with the Standard RJ motor.

In the manual you reference it said Standard (all models), not Standard RJ. It says: The Red Jacket= not required. It also shows illustrations with both Swift check valve and with no Swift check valve installed.

Red Jacket used "Standard" to describe both old and new STPs.

If it has a functional element it gets a swift check. Adjustable pressurestat doesn't need it.

RJ Standard, RJ Quantum, and The Red Jacket. Standard and Quantum are what I would consider “older style RJ”. The Red Jacket is the newer style. All of which can be used with or without swiftcheck valve. You can even use functional elements, just have to modify them if wanting to test 0.2 & 0.1 GPH. 3.0 GPH.

Quantum and The Red Jacket you can use a spike check.

Regardless of the debate, right or wrong, just be on the safe side and use swiftcheck valve .
