Rebuilding pressure regulators?

[DPX22]

Are you able to rebuild these pressure regulators? I am having one or two leaking water from the back and have read that it is possible, but this would be my first time trying to maintain one. Are there any signs I should be aware of that would point to a replacement vs. rebuild?

The only reason I ask is because there's alot of warning stickers everywhere and I know it's job is to, regulate pressure. I really would like to have a second opinion before I open one up and put it back together.

To avoid downtime I'd recommend replacing it and rebuilding the old one to have as a backup.

Great, thanks for your reply as well as the link!

I'll go ahead and purchase a new one for replacement while I rebuild the old one.

For the build portion, I'm assuming everything the kit comes with gets replaced and nothing special is involved?

I've never rebuilt one of those, but it's always possible with a brass regulator with steel hardware that something is rusted, corroded, or eroded beyond repair. You'll just have to see once you get it apart.
