Don’t Let Marine Plumbing Problems Sink Your Season: What to Watch for and How to Fix Them
Boaters know that a reliable plumbing system is essential for safety and comfort on the water. Yet, some of the most common issues—cracked hoses, failing bilge pumps, and corroded fittings—often go unnoticed until they cause real trouble. Here’s what to watch for, why these problems matter, and how Lighthouse Marine Supply can help you keep your boat in top shape.
CRACKED HOSES: SMALL LEAKS, BIG HEADACHES
What’s the risk?
Marine hoses carry everything from freshwater to waste and fuel. Over time, exposure to sun, salt, and vibration can cause hoses to crack or become brittle. Even a small split
can lead to leaks, water damage, or hazardous fuel spills.
Warning signs:
We stock a full range of high-performance hoses designed to withstand the harshest environments. Whether you need sanitation, fuel, or water lines, our team will help you
find the right size and material for your boat.
FAILING BILGE PUMP: THE LAST LINE OF DEFENSE
What’s the risk?
Your bilge pump is your boat’s safety net, keeping unwanted water out of the hull. If it fails, even a minor leak can become a major emergency—especially if you’re far from
shore.
Warning signs:
Lighthouse Marine Supply carries top-quality bilge pumps, float switches, and wiring kits. Not sure what capacity you need? Our experts will guide you to the right solution
for your vessel’s size and usage.
CORRODED FITTINGS : THE HIDDEN WEAK LINK
What’s the risk?
Fittings connect hoses, tanks, and pumps throughout your boat. If these corrode—especially below the waterline—they can fail suddenly, causing leaks, loss of system
integrity, or even sinking.
Warning signs:
We offer a wide selection of corrosion-resistant fittings in marine-grade bronze, stainless steel, and reinforced plastics. Our team can help you match the right fitting to your
application, ensuring safety and long-term reliability.
Stay Ahead of Plumbing Problems
Routine inspection and timely replacement are key to avoiding these common marine plumbing headaches. At Lighthouse Marine Supply, we’re here to make sure you have access to the best parts, expert advice, and fast shipping—so you can focus on enjoying your time on the water.
