Boat Hut Insight
When fitting a pressure relief valve on a boat, remember that saltwater environments can accelerate corrosion. Opting for brass components, like the ones included here, is a smart choice because brass resists corrosion better than many other metals. Also, consider the ease of access for future valve inspections or replacements – cramped engine rooms often make maintenance a real challenge. If you’re retrofitting, double-check that your existing plumbing and fittings match the thread size and pressure rating to avoid leaks or valve failure. And a cheeky tip: always keep a spare valve onboard – it’s the one part you don’t want to be without when you’re offshore.
