Review on Enhanced Water Valve Kit 385311641 for Sealand 300 310 320 Series Marine Toilet Replacement - Durable Plastic Construction by Darrell Beecher

Dometic valve pictured above. I figured I'd save some money and buy the cheaper $13 version but it had trouble opening to flush the toilet and then only lasted 2 months before it started opening and flooding the toilet . I wasn't home and my daughter had to run outside and turn off the water to prevent a spill! I replaced it with a Dometic valve and noticed a few things. The clips that lock it in place aren't as thick as the OEM clips and aren't in exactly the same position. This caused the valve to sometimes not open when the lever was pushed. This issue was corrected by the OEM who put in 2 screws to hold it in place and the push button valve is much easier to push onto the OEM. So less resistance plus the screws holding it in place means it will open and let water through before the drain valve opens. The valve on this does not slide smoothly in the barrel, contributing to its jamming in the open position. Save time and nerves and just buy a good one.
