Hey guys. I’ve used one of these before. My dad installed the last one so I wasn’t sure how these are supposed to go. I know this is a really stupid question. But I just flipped on my RO/DI and it leaks out the back fittings. I didn’t like my chances for this actually sealing when I installed it and it of course leaks. Should these just work fine or do I have it in wrong? Are there fittings you can buy at a hardware store that would work better than these plastic rings? It’s just a plastic cap that fits over the tubing and then a plastic lock ring thats supposed to tighten down. I don’t get how this is supposed to work. It has to allow flow to the tank but it’s supposed to stop flow once the float rises. I understand the float blocking the flow but on the back on the outside of the storage tank, these fittings just suck.
