Just installed one of these and it worked without any issues **Q: How do i connect it to watts premier wp-5? The system gas it's own aso inside, air-gap faucet and tank line is 3/8, not 1/4?** A: If your supply/ return lines are 3/8ths od and the valve is 1/4 od this is probably not the valve you need, suggest you contact the manufacturer of your filter for a suitable replacement **Q: Is there any warranty on this?** A: This has worked very well for me since purchase some years ago. It replaced a defective unit on my RO system. At the price point - if it died now at 4 years - I'd have no complaints. But it marches on. So just drop the hammer on it, and move on. **Q: Have 5 stage ro, upgraded tank to 80 gallon. works fine. now added 2nd membrane and 2nd 120 gallon tank. reject water never stops. how to fix ?** A: It needs to be able to build pressure for it to shut off. Your tank may not be building any pressure check to make sure you don't have any leaks in the tank ## Frequently Bought Together - DIGITEN 1/4" Automatic Shut-Off Valve with Quick-Connect Fittings For RO Reverse Osmosis(Pack of 2) - APEC Water Systems 1/4" Quick Connect Check Valve Replacement Part (Check-VAL) - DIGITEN 50GPD Flow Restrictor 300CC 1/4" Quick Connect for RO Reverse Osmosis (pack of 2) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hk/products/38497956-1-4-automatic-shut-off-valve-with-quick-connect-fittings](https://www.desertcart.hk/products/38497956-1-4-automatic-shut-off-valve-with-quick-connect-fittings) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-07-21*
