MetCheck Double Check Backflow Preventer – Reliable Medium Hazard Protection
Backflow prevention valves designed to last a lifetime.
MetCheck DCV Information
The MetCheck Double Check Valve is a medium-hazard backflow prevention device engineered to protect potable water systems from contamination caused by backsiphonage or backpressure. Featuring dual check mechanisms for increased safety, this valve is ideal for commercial and industrial mains where regulatory compliance and longevity are essential.
How it works
A double check valve uses two independent check mechanisms in series to stop reverse flow. If one check fails, the second still prevents backflow — making it far more reliable than a single check valve alone.
- Superior Durability: Our 316 stainless steel construction ensures long-lasting performance and reliability. Unlike traditional ductile iron valves, they are highly resistant to corrosion, paint chipping, and other forms of degradation.
- Easy Installation and Maintenance: Our user-friendly design and coupling joiners simplify installation and maintenance processes.
- Versatile Sizing: Available in a range of sizes from 65mm to 150mm with both AS2129 Table E or AS4087 PN16, our valves cater to diverse applications.
By choosing the MetCheck Double Check valve, you’re not just selecting a product; you’re investing in the health and safety of your water supply.

| The valve Body is made from 316 Sch10 Stainless Steel to ensure the maximum resistance to corrosion with no rusting internal debris or blistering paint passing through checks, damaging seals, or causing severe damage to the internal componentry. |
| Earth support tags can be supplied if current is suspected to be within the valve assembly of the pipe line. Earth leakage can reduce the life span of any valve assembly due to osmosis which will attack the valves close to weld lines. |
| Full back up technical support from the Manufacturer. |
| Made in Queensland with quick access to all spare parts and accessories for every application. |
| Hydromet Valves are high pressure rated to PN16 in all models. |
| Valves come with optional strainer boxes, valve support stands, Met-Coated Nuts and Bolts anti-galling specific for high tension applications, and numerous J and S -Pipe rises all in 316 Stainless Steel to accommodate a full assembly. |
| Ribbed seal anti-slip gaskets purposely designed by Hydromet. |
| Due to the lightweight 316 Sch10 Stainless Steel design the Hydromet Valves are among the lightest Backflow preventers on the Market. |
| The Valves are designed for ease of access and adjustment, having been built with roll groove couplings. This enables the plumber to completely pull apart and reassemble the Valve with just a Spanner. |
| 5 Year warranty on the main body and a 12 Month Warranty on all moving parts. We are unable to cover components that are shown to be damaged by debris, or incorrect installation. E.g. installation for an electric cut off switch downstream causing corrosion. |
| Lead free |
| Horizontal or vertical installation |
| Top-mounted test taps to ensure ease of use when testing testing |
| Maximum Working Pressure | 1600 kpa |
| Maximum Working Temperature | 60 deg C |
Hydromet commissioned AWQC to conduct an updated testing program of sampled components supplied into the marketplace on behalf of Hydromet. With the result of this testing program conforming with the requirements of AS/NZS 4020.
- WaterMark Certification
- NATA approved test reports ensure the quality and compliance of over 40 MiniMet and MetCheck backflow prevention valve models, upholding WaterMark certification. These valves are certified on the Hydromet WM license WM-022473 and Hydromet are subject to annual surveillance by IAPMO Oceania for continued compliance with the WaterMark Certification Scheme.
AS/NZS 2845.1 – MiniMet and MetCheck valves are compliant with AS/NZS 2845.1. All MiniMet and MetCheck valves have a classification of either a low or medium hazard rating, as defined in Volume 3 of the NCC, the Plumbing Code of Australia. This product complies with the Lead Free requirements of the National Construction Code, Volume 3 (PCA)
Flanged stainless steel pipework – The AS/NZS 4020 test reports also extend to cover the various SS316 flanged pipes manufactured by Hydromet, with these components being available to suit the installation of any backflow prevention valve or water meter assemblies.
