9 Tips for Avoiding Costly Marine Plumbing Repairs


The Mobile Mariner | Jensen Beach | Florida | Marine Plumbing | Avoiding Costs

It is important to make sure everything on your boat is working right, including your plumbing system. Keeping your marine plumbing in good condition is vital to the operation of your vessel. Most boat owners can handle basic plumbing, so to ensure you take the rights steps - we've put together this list of inspections for you to follow.


Visual Marine Plumbing Inspection:


Always start by with a visual inspection. Physically inspect all the accessible plumbing connections and lines, checking for signs of corrosion, damage, or leaks. A visual inspection will also help you sight disconnected or loose hoses, clamps, and fittings.

Water Pump Inspection:

Your next step is to test the water pump. Turn on your water system and listen for odd or unusual vibrations or noises. This could be evidence of a problem with your water pump. You need to ensure your water pump is not only securely mounted but that it is properly connect to the electrical system.


Electrical Inspection:


Believe it or not, your electrical plays an important role with your plumbing system. Hit all your switches. Make sure they all turn on and off. Checking your electrical switches should be an everyday check when you board your boat, whether you're checking for your plumbing or not. If your electricity supply is low, it can affect how well your pumps work. Your freshwater pump, macerator pump, and shower sump pump all run off electricity.


While there is an option to have a manual pump (there are even manual macerator pumps), some will still go with an electric pump for convenience.


Hose Inspection:


Examine all your hoses carefully. Look for any bulging, cracks, or deterioration. Exposure to the elements can cause your hoses to degrade. Replacing word or damaged hoses will not only prevent leaks, but it will prevent (potential) system failure.


Seacocks and Valves Inspection:

Inspect your seacocks and valves to ensure they operate smoothly. They should open and close without difficulty. Lubricating the valves will help, and don't forget to replace any that are malfunctioning or corroded.


Pressure Test:

Consider pressure testing your marine plumbing system if you suspect leaks. Pressurize the system with air and use soapy water to detect bubbles where there are leaks. Early detection and fixing of leaks can avoid bigger plumbing problems and keep your boat running smoothly.



Sanitary System Inspection:

If you have a marine toilet on your boat, inspect the hoses, seals, and pump for leaks, odors, or blockages. Flush the system with fresh water and use chemicals to prevent odor and build-up.



System Flush:

Flushing your plumbing system periodically with fresh water will remove salt and mineral deposits, which can accumulate in your pipes. If you don't have a freshwater flush available, disconnect the shore water connection and run fresh water through your system for a few minutes.


Bilge Pump and Drainage Inspection:

Inspecting your bilge pump should be routine before cruising the big blue. Always make sure that it is properly functioning and that no blockages are in the discharge line. Also, check your drainage systems (like your deck drains and cockpit scuppers) to verify that they are free and clear of debris.


Routine Maintenance:


Remember that proper maintenance and regular checks of your marine plumbing system are essential to ensure the safety and functionality of your vessel. If you're unsure about any aspect of your boat's plumbing, it's a good idea to consult with a marine technician or professional for assistance.


Not only will this keep your boat running smoothly, but it will also ensure that your freshwater supply remains uncontaminated and that all of your pumps are working correctly. Don't take any chances with the safety of your boat.


When you work with The Mobile Mariner, you are choosing quality work from a dedicated team. We understand that it takes a thorough inspection of a marine plumbing system to see every aspect of it. We will inspect and make any necessary marine plumbing repairs or replacements as needed.
