    Things to Consider Before Buying a Washdown Pump

    If you are asking yourself what the best saltwater washdown pump is, then you may need to answer the question from multiple angles. There are a few factors you need to consider before labeling one as the best option for you. Here’s a list of how to do it.

    The Higher the Pressure, the Better

    If the washdown pump doesn’t produce enough pressure per Square Inch area, then it’s probably not your worth. A standard-functioning machine will be delivering a water pressure of around 60 to 70 PSI.

    Any pressure below that may be considered as below the satisfactory level. Look for the one that has the capacity to deliver more than 65 PSI. It’s the best if its 70 PSI.

    Speed Is Always the Key Factor

    Let’s get this straight. You are trying to pump water and other junks that are mixed up with it out of your boat-deck. The sooner you can do it, the better it is for you,which calls for a higher speed of draining.

    An average washdown pump may clear off dirty water at a speed of about 3.5 to 5 GPM. Of course, you should look for the highest GPM to be on the safe side. To select the best one, always make sure that it can drain out at a speed of around 4.5 or more GPM.

    Built-In Thermal Control Can Save Your Pump

    Obviously, thepump runs with a lot of air pressure to suck out water from your boat surface. This makes the machine heat up quickly. That’s why most of the pumps suggest intermittent pumping.

    However, the latest models come with a built-in thermal control system. Whenever the machine gets heat up to a certain level while running, it will detect it and switch itself off.

    It will wait until the machine comes back to a normal temperature position. Once it comes back to normal, the machine restarts itself. This option can be very crucial for your pump’s health. You should definitely place it on your check-list before making the purchase.

    Make Sure Its Corrosion Resistant

    A washdown water pump works with seawater, mainly. This definitely means that it is going to be exposed to salty water. Coming into contact with saltwater on a frequent basis, poses the pump under threat of corrosion and rust.

    To solve this issue, some of the washdown pumps have protection against such corrosion.Some of them are made from ABS engineering plastic that not only allows the device to have rust and corrosion-resistant features but also a sturdy build.

    Go Noise-Free

    Pumps are very popular for their noise-making traits. Of course, it's a machine, and it is likely to make noise while in use. But there is room for updating it as well. 

    There area number of pumps that have a low-noise producing capacity. Some even go completely noise-less. That’s a great feature to have at the same price as other noise-making ones. Don’t miss this out.

    An Automated Pressure Switch Is Smarter

    Nowadays, many pumps come with automated pressure switches. This pressure switch is smartly integrated with their nozzles. It starts and goes off according to the nozzle’s opening and closing.

    Whenever the nozzle opens, the pressure switch starts and goes off the moment the nozzle is closed. This saves a lot of power and accelerates the longevity of the pump.

    How to Install a Saltwater Washdown Pump?

    Installing a saltwater washdown pump is not hard. You need to follow a few simple steps to get the pump going within minutes.

    After selecting the device that suits your purpose, you need to mount it on your boat.

    First, you need to mount the pump in a drier place of the bilge, which can be about five to six feet from the water intake. Still, allow enough space for placing the water strainer over the inlet part.

    Now, from the sides of the outlet T-fitting, you need to route its hose to front and back termination locations. The front one can be mounted on an anchor locker while the back one should be on the bulkhead of the transom walk through.

    Now you need to connect the intake hose’s head to one of the sides of the check valve. Connect the other side to a hose part running to the inlet port of the water strainer. Again, you need to run another section of the hose from the outlet of the strainer to the inlet part.

    From the outlet T-fittings, you need to run the hoses towards the holes that are drilled for connecting bulkhead fittings.

    Use clamps every 18 inches on the hoses. Pull out the hoses via the holes, and do a double clamping. After you are done with this, install all the fittings in the deck.

    Finally, connect the pump to a DC power distribution to make it start working right away.
