Review on Freeze Resistant Upgrade Kit 385311641 for Dometic Toilets 300, 310, and 320 - Innovative Double O Ring Technology Prevents Leaks by Jay Matlock

Our valve started leaking in February after a Snovid-21 in Texas. Normally we don't need to prepare for winter as we rarely get below freezing but due to the unprecedented low temperatures this year we drained the water heater and blew out the pipes before the winter storm hit. We thought we avoided damage, but it turned out our Dometic valve had failed. I appreciated the brand name and was shocked at how much this little valve costs. This piece was identical to the one we removed. It was easy to install (except the spot was difficult to reach) and solved our problem. Ideal!
