My combi system has cold leak of 0.5bar/8hr. This valve doesn’t seem to raise the pressure at all.** A: I have no problem with this valve it appears to have a good flow and did not need setting from memory the grey knob is a shut off, check the direction, you would have have two isolation valves in the system before fitting check them. The quarter turn plastic lever ones I have seen them strip and stay shut. Could be the strainer basket is blocked. ## Frequently Bought Together - Caleffi 553140 Automatic Filling Unit 1/2'' with Manual Cock, Strainer, Check Valve.and Pressure Gauge - 1/2" x 1/2" inch Union Pipe Connection Pipe Nipple Wire Carpenter Brass Fitting BSP Male --- ## 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.com.pa/products/103795985-caleffi-553140-automatic-filling-unit-1-2-with-manual-cock](https://www.desertcart.com.pa/products/103795985-caleffi-553140-automatic-filling-unit-1-2-with-manual-cock) --- *Product available on Desertcart Panama* *Store origin: PA* *Last updated: 2026-10-21*
