Best Boat Shower Pumps Sumps Buying Guide & Reviews of 2020

The ingestion of water into a boat is common and unavoidable. However, it does not mean that you are safe. The water can enter your boat through multiple sources such as physical damage or melting of ice from the icebox. The boat shower pump sumps are your best bet to expel the water from your boat. Our buying guide will throw light on the factors you need to account for before purchasing a boat shower pump sump.

Types

Centrifugal Boat Shower Pump Sumps

Commonly referred to as electric pump sumps, they need to be submerged in the water in order to expel it. They are relatively inexpensive and very easy to install. They come with a built-in strainer that filters all the debris. The stainer can be removed and cleaned easily to prevent the clogging of water. However, they won't be able to expel the last a few ounces of water and become inoperable when the boat’s electric system fails. So, it is not wise to rely solely on electric pump sumps.

Diaphragm Boat Shower Pump Sumps

Commonly referred to as manual pump sumps, they do not require to be submerged in the water. The manual pump sumps do a great job of expelling huge gallons of water. They can lift the water through an intake hose and expel it outside. Valves are used to regulate the volume of water that is sucked through the house and expelled. The strainer has to be fixed externally at the end of the hose to filter the debris to prevent clogging. However, using the manual pump sump requires an enormous amount of physical strength, and it might look like a herculean task at times.

Automatic Boat Shower Pump Sumps

You can convert your centrifugal or diaphragm boat shower pump sump to automatic by installing a bilge pump with a water sensing switch. The performance of automatic pump sumps is below par compared to its counterparts. They are only capable of removing small amounts of water. They come with a remote monitoring system to overlook the condition and performance of the pump sumps.

Features

Compatibility

The pump sump you intend to fix to your boat should be able to serve its sole purpose of expelling the water from the boat. Not every boat takes in the same amount of water. A speed boat takes in more water compared to a large boat that usually sails in calm lakes. So, the former requires a more efficient pump compared to the latter.

Weight

Always opt for a boat shower pumps sump that is lightweight and smaller in size. You do not want to add additional unnecessary weight to your boat nor cramp the boat for some room.

Installation

Some boat shower pumps sumps can be installed by yourself while some may require a professional. Go with the one that can be installed easily to your boat.

Mesh Filter/ Strainer

The mesh filter or the strainer that comes with the pump sumps should be easy to clean. If it is not cleaned properly, the pump will be clogged and rendered ineffective.

Price

Their cost ranges from $30 to $250.

Warranty

Almost all the brands offer a warranty on their boat pump sump models ranging from 1 year to 5 years.

Conclusion

Leaving your boat even with small quantities of water, can pose a serious threat to your safety. It can destabilize the boat or cause a short circuit in your boat’s electrical system. You need to have a top-notch boat shower pump sump fitted to your boat to clear the water. Where else you will find a top-notch boat shower pump sumps other than the top ten list we have created for your ease.
