The wrong assembly of the spring will cause damage to the piston seat when manual deflation is pressed. Inside the piston is a hemissphere on which the flat side of the spring has to go. So the spring can move sideways without conducting sideways force to the piston when manual deflation is pressed. I once got a wrong assembled ex valve from sitech... some teeth were broken, causing leakage...
There's a few instructions on disassembly kicking around but this is the first one that goes into popping the bottom half off. Thanks so much for sharing. On mine, I actually had to bore a 64mm hole in a block of wood and pop the base in a bench vise rather than by thumb and hand per
Thank you so much for this video! My dump valve on Waterproof suit started leaking so I had to take it apart. There was some fine silt inside everywhere. This video helped me a lot to disassemble it quickly and without breaking anything!
Small points: 1) The small piston like center guide goes to the bottom of the spring, not the top as shown in the video. This is according to SiTech's exploded view of the unit I also placed the plastic disk that fits the spring to the bottom as it seems to help guide the small piston like center guide. This small ring that obviously fits the spring is not identified in the SiTech document; and, 2) The basket adjustment lid that tensions the unit goes in more cleanly if you engage the three prongs from the retainer into it and also carefully locate the female screw down just prior to the receiving threads. Then when you push down on the adjustment lid and simultaneously turn the base unit it engages immediately.
just took mine apart and noticed the black ring that goes inside the spring was on the opposite end of the spring. Hopefully this will resolve the leak issue I have been having and had pretty much narrowed down to the valve. Was about to buy a new valve so this was was a pretty much take it apart what have I got to loose. IF it resolve the issue I will buy you a beer
Wish I had seen this video BEFORE I was told by the shop keepers and dry suit shop that Si-Tech/Bare exhaust valves are non-serviceable and spent CAD$85. Its perfectly serviceable and cleans up nicely with the help of these instructions. Thanks Jackson Light!
