Frequently Asked Question

1. What is a shower sump?

Shower sump systems designed for handling grey waste water from sinks and showers, etc. They have multiple inlet ports and feature an integrated waste pump.

2. What is a sump pump on a boat?

A boat sump pump system – aka a bilge pump or marine pump – is a good choice for keeping and draining water from your boat. Marine sump pumps are always a good idea for any boat that has on board showers, toilets or other water system.

3. What is a shower sump on a boat?

If you are not familiar with the workings of a basic shower sump system on a boat, it is actually pretty simple. The drain at the bottom of the shower empties into a box down in the bilge. Since the box is most likely below water level, there is a pump in the box that pumps the water up, out and overboard.

4. How does a boat shower drain work?

In this simple operation, the faucet controls the water pressure; the water flows from the showerhead and is collected in the shower drain sump; the water level activates the sump pump float switch that turns on the water pump to empty the sump.
