The Polymaster Ball Valve/Outlet Upgrade – BV1.5A provides a convenient solution for upgrading your Polymaster tank or fitting configuration from the standard 25 mm (1″) outlet and ball valve to a larger 40 mm (1 ½″) brass outlet with matching ball valve.

• Ideal for use with rainwater tanks, bulk storage systems or any installation needing higher throughput.

• Simple threaded installation — integrates with Polymaster standard BSP fittings.

Overview:
This upgrade accessory allows you to easily boost the outlet capacity of your Polymaster system without extensive plumbing changes. By moving up to a 40 mm outlet and ball valve, you can reduce restriction and improve flow rates for larger pumps, irrigation setups or high‑use water systems. Perfect when the standard 25 mm outlet isn’t sufficient for your application.
