Whale Watermaster Inlet Socket with Integrated Pressure Switch – White (ES5001B)

Whale Watermaster Inlet Socket with Integrated Pressure Switch – White

A genuine Whale Watermaster inlet socket with integrated pressure switch in white — a direct replacement for the socket in older Whale Watermaster submersible pump installations. The integrated pressure switch automatically activates the pump when a tap is opened, providing seamless, automatic water delivery throughout your caravan or motorhome.

Key Features

• Genuine Whale Watermaster replacement component
• Integrated pressure switch — automatically activates pump when water flow is detected
• White finish — suits older Whale Watermaster installations
• Like-for-like replacement for existing ES5001 socket installations
• Suitable for caravan, motorhome, and campervan water systems
• Restores full automatic pump operation

ES5001B vs ES6001B — Which Do You Need?

The ES5001B is the inlet socket for older Whale Watermaster installations without the Easi-Slide feature. If your pump slides in and out of the socket without tools, you have an Easi-Slide system and need the ES6001B instead. Check your existing socket before ordering — contact us if you’re unsure.

About the Pressure Switch

The integrated pressure switch detects when a tap is opened and automatically starts the pump — no manual switching required. When the tap is closed, the pump stops automatically, conserving battery power and preventing the pump from running dry.
