Rule Shower Drain Pump Systems Information
The Rule Shower Drain Pump Systems collect grey water from your shower or sinks and automatically pumps the water out of the boat. The shower drain boxes contain a high-quality Rule bilge pump along with a Rule float switch, a removable filter strainer, a non-return valve and multiple threaded inlet connections.
When the float switch is operated the ignition protected Rule Submersible Bilge Pumps, sucking the water out of the sump and out of the boat.
The shower drain sump features a sealed clip-on transparent lid for ease of access to the pump and an easily removable filter for cleaning out unwanted hair or debris. The sump boxes have 3 threaded inlet connections, two of which are blanked off until required, a threaded outlet connection with a built-in non-return valve and 5 threaded hose tails in various sizes, 2 x 19mm (3/4"), 1 x 25mm (1") and 2 x 29mm (1 1/8"), extra straight hose tails or right angle hose tails can be bought separately.
The Rule Shower Box is easy to install thanks to its independently mountable rear bracket which can be screwed into tight spaces before the sump box is fitted, leaving just the front screws to install.
The shower water sump box has 2 pre-stripped wires for installation via an adequate fuse and a separate switch if required.
Why Buy a Rule Shower Drain Box?
These Rule shower drain boxes were redesigned in 2018 to make them more user friendly and better quality compared to their cheap shower sump competitors. These new models are not direct replacements to the original Rule Shower Drain Boxes as these models are smaller.
The main advantages of a Rule Shower Drain Box are:
- Screw on threaded hose tails making installation easier and quicker.
- A non-return valve in the outlet from the pump to stop backflow into the sump box.
- A high quality rigid strainer that slides nicely into place.
- High Quality Rule Bilge Pump & Float Switch.
- An easily removable clip-on lid.
