It just happened to me. Sent my drysuit in to Bare (via my LDS) to get a quickneck and new boots installed.
First dive afterwards I descended to 8 m, went to adjust my dump valve and it came unscrewed in my hand. The inner portion slid over a bit so I couldn't get it rethreaded and tightened at depth or easily at the surface, with lots of water pouring in each time I tried. I'm assuming they took it off and never retightened it correctly.
Needed to swim back to shore while holding the valve in place, where I could get my shoulder high enough above water so I could easily adjust the inner portion without more water coming in and screw it back together. Swam back out and completed a cold, wet dive as the water migrated all around my suit. At the end of the dive only my feet and right arm were dry. Walking back to the parking lot saw water run down to my feet and get them soaked too. I dumped out a couple litres of water and still had very heavy soaked undergarments.
The good news is after a thorough drying the suit is now leak free and better than ever.
Moral of the story - check your gear after servicing - especially if you are about to head out on a trip.
I should add that all the servicing my LDS has done in-house on my regs has been flawless, never an issue with them.
