Hi All, Is there a code reference on the maximum amount of time allowed to close a wall PIV (or any valve for that matter)?
I have a Wall PIV that is hard and slow to turn, and takes about 30 minutes of fighting to fully close. Servicing of accessible components has not helped.
I probably won't be able to get funds to repair/replace unless I can quote a code violation.
I have only found a minimum amount of time, but nothing for a maximum. Thanks in advance!

Nothing I am aware of. Minimum is 5 seconds, that I know.

If this valve needs to be closed in an emergency, 30 minutes of uncontrolled flow can cause a lot of water damage, and disrupt operations/productivity for an indefinite period of time. Perhaps a replacement could be justified on this basis?

The minimum is to avoid a waterhammer effect if closing too quick.

You might be able to use NFPA 25 Chapter 13 as a valve that has been damaged. Any time of coercion or supplemental lubricant requirement are proof of a damaged valve. But as for a hard and fast rule about timing, I am not aware of one.

I think you might be coming at this from the wrong angle. The minimum time requirement (to my knowledge) is to prevent water hammer.

Clearly the valve is damaged. While you may not find a coed reference, having the purse holders consider 30 minutes of uncontrolled water flowing inside the facility as someone wrestles the valve.

This should definitely be repaired or replaced for many reasons.

Thanks, as "unreasonable force" is necessary to operate the valve, I can reference this code as need for repair.

Since it's clear we all agree that this is unacceptable, here are some of my thoughts on how a contractor should handle this kind of situation to protect their liability.

NFPA 13, 2022

This is a crooked valve, get it repaired or replaced.
