Now that you have purchased the best marine freshwater pump follow this step-by-step guide on how to install a marine freshwater pump
If you are replacing the existing RV water pump, the first logical step would be to locate it. The easiest way of locating the pump is by listening to hear the sound the pump produces when running. In recreational vehicles, the pump is mostly found outside the vehicle and closer to the water tank.
Once you locate the pump, drain it thoroughly to remove all the residue present.
Switch off the power supply to the existing pump. Use a screwdriver to remove all wirings connected to the pump. Also, disconnect all the hoses, screws, and bolts attached to the pump.
Remove the old pump. Take out your new replacement and place it where the old one was. Secure it tightly using a screwdriver. Use some Teflon tapes to wrap the pipe threads. Then connect the outlet and inlet hoses, then secure them using the clamps.
Reconnect the marine fresh water pump to the pump link and the wires. Then reconnect the power supply to the pump. Finally, test the pump to ensure it is working.
The Benefits of a Fresh Water Pump (why do you need a marine water pump?)
Marine freshwater pumps are suitable investments since they guarantee different perks on your adventures. Some of the benefits of owning the marine freshwater pump include;
What to Consider When Purchasing a Marine Fresh Water Pump
1. The type of Fresh Water Pump
It is essential to know that there a couple of options for a freshwater pump. There are 12V and 24V pumps. The 12V options are known to run silently. They take up less space and consume less electricity from the batteries compared to those with high voltages. Unfortunately, they generate low pressure, which means they produce low gallon-per-minute rates.
Alternatively, 24V pumps can offer higher water pressure. They can provide more reliable performance for a longer time. Ultimately, they are the best option for heavy-duty applications. You should know that they require scheduled regular maintenance to be able to function optimally. The 24V options use high energy amounts, placing a massive load on your batteries.
2. Size and Installation
Even if you choose a reliable and robust pump, it will be utterly worthless if you cannot install it. Unless you hire a professional to help with installations every time, you should consider a pump that is easy to install. The same applies to the size of the pump and the space for fitting.
If the freshwater pump can't fit in the designated space, it will not help. You should pick options that offer easy installation and application without needing external aid every time. The options should be easy to transport to the designated location. The amount of space you will be installing the pump in is also essential.
3. Suction power and noise level
It would be best if you considered options that can operate with minimal noise. For this, you should consider five-chamber pump designs. The five-chamber designs have sound dampening capabilities, making them suitable for reducing noise levels. You can also check to see it; they have rubber feet, which is vital in reducing vibration levels.
If you consider this noise-reduction feature impossible, you should pay immense attention to the mounting type your pump needs. The mounting type should use a noise-absorbing system since it allows the pump to work quietly.
A vertical suction lift shows the water amounts your pump requires when functioning to run more efficiently. You should note that this differs from your water requirements. For instance, if you require minimal water amounts and your pump does not need to apply excess suction power, then you are better off with a pump that has little suction lift.
4. Pressure Ratings and GPH
Both these factors have a significant impact on your pump's water output. The water pump's pressure ratings inform you of the resistance levels it can withstand. This can be determined either via PSI or bar units. On the other hand, gallons per minute depict the water amount the water pump can churn out at a given time. It would be best to consider a freshwater pump with at least 1 gallon of water per minute flow rate.
If your water application requirements are high, you can choose options that offer two or three gallons per minute flow rates.
5. Auto Switch and Pump Cycle
These features ensure the protection of your pump system. The majority of buyers consider these options even though they add costs. Whenever the pre-set value is achieved, the pump cycle shuts down the pump. Sometimes the pump continues to provide a flow rate that is lower than the pre-set value.
At that moment, the pump cycle becomes more critical. The pump cycle reactivates the pump once the readings go lower than the pre-set value. The pump cycle ensures you achieve the optimum flow rate at all times.
Pumps that feature integral automatic switches help to provide more protection against overheating. Once the water pump achieves the pre-set value, the automatic switch deactivates the pump automatically. It ensures the durability and protection of the device as well as keeping your energy bills low.
Who Needs a Marine Fresh Water Pump?
A marine freshwater pump is for the ideal traveler. Whether you own a boat or a recreational vehicle, it is your best friend when it comes to water needs. It has many applications, the most important one being the delivery and pumping of water. The majority of the pumps are versatile and can be used for marine and agricultural purposes.
FAQs About the Marine Fresh Water Pump
Q: How does a marine freshwater pump work?
A: The most modern models come with a pressure switch that allows the unit to build up pressure in the freshwater line. Whenever water is in demand, the spigot is opened, and a current of pressurized water is availed. It is responsible for activating to sustain the required pressure.
Q: How do I prime a marine freshwater pump on an RV or boat?
A: Priming can be done by filling the suction pipe and the pump chamber with water. This can be done by pouring water via the hand pump's exit spout while stroking the handle in a downward and upward approach.
Getting freshwater from tanks to sinks, showers, and faucets is critical for any boat, campers, or recreational vehicle.
