Readers Comments is a place for your thoughts on products, places and things that are the subject of NFTB articles. Send us your feedback, and we will do our best to a) share your comments with fellow readers and b) help you obtain answers to questions.

Below please find this month’s readers comment, and the manufacturer’s response.


NFTB’s article on the Sea Joule Solar Bilge Pump continues to be popular among readers.

An early version of the Sea Joule Solar Bilge Pump

We recently received the first negative comment about the product, which prompted us to contact the manufacturer. In fairness to the manufacturer, our initial review did include the following manufacturer’s recommendation:

“The manufacturer advises against submerging the pump underwater.  This is because, while all wire connections within the unit are watertight sealed, the battery terminals could be exposed if either a) the unit were to be placed under several feet of water or b) the unit is placed upside down under water.  Neither of these scenarios is likely to happen with normal use.  We repeatedly submerged the installed unit in seawater with no adverse affects.”

NFTB continues to test an early version of the Sea Joule pump that is in its third season.

Readers Comment

Dear NFTB:

My experience is that this (the Sea Joule Solar Bilge Pump) is not a pump to be used at sea. The first one I purchased and its replacement both corroded within a couple of months. The connections on top of the battery corroded right through. I had the version with the remote solar panel, and the connection between the panel and the pump also corroded right through. Moreover, the panel itself was not watertight, and both the original and the replacement deteriorated internally within a couple of months. The pump has a beautiful case, including a nice watertight rubber seal on the top. There is, however a big hole in the bottom so that seawater can flow around all the electrical parts, which appear to have no protection whatever.


Manufacturer’s Response

Dear NFTB,

Thank you for referring your reader’s comment. While we have not personally seen the unit in question, when we learned of this possible problem we made a precautionary change to the Sea Joule Bilge Pump assembly, and added silicone sealant to both battery connections. All wire connections are now made with watertight heat shrink connectors.
