A bilge pump trouble shooting

What’s the mainly issues for the bilge pump?

1. The pump has power but won’t pump water, and switches itself on and off intermittently.

2. The pump has power and water in the bilge, but the pump won’t move the water.

Here is the suggestion for how to solve it.

1. Check the bilge pump has been installed correctly

When installing a bilge pump, it is important that the outlet hose is always on a gradual incline without any kinks or dips. Unnecessary loops and sags can cause airlocks, which will prevent effective bilge pump performance. 

Here recommend to add a anti-siphon loop with a one-way valve in the outlet hose  to prevent the backflow of water.

2. Check if your bilge pump is blocked

Most bilge pumps will come with a strainer to trap any foreign chunks before they can interfere with the impeller. This could be just about anything, but a recurring culprit seems to be little offcuts of marine carpet. As a general rule, if you think your pump is broken or not operating as it should be, first look for a fouled impeller or rubbish in the pump.

3.Check the bilge pump wiring

While there are many reasons a pump may fail, a common cause for early bilge pump failure is corrosion of the wires that power the pump. In a marine environment, even though the wire is coated, water can still enter through any nicks in the plastic or where the connection to the pump is made. Over time, this will lead to hidden corrosion in the wires, and can destroy the entire wire length inside the plastic insulation. The result is wiring that appears to have no problem but, in fact, cannot deliver power to the pump and must be replaced.

 After you check all the possible problem, but still cant solve it, You can consider to replace a new bilge pump.
