Large 24V Shower Sump Pump System MK2

Name: Large 24V Shower Sump Pump System Mk2
Price: 164.95 GBP
Rating: 5 (1 reviews)

Premium 800 GPH High-Capacity Marine Drainage

The Attwood MK2 Shower Sump Pump System is engineered to handle the high-volume drainage requirements of modern marine freshwater systems. This "Large Box" version provides extra capacity to prevent overflows from multiple sources like showers, galley sinks, and dishwashers simultaneously.

INNOVATION: Featuring the patented X-Air™ Impeller, this system forces air bubbles out of the pump and pipework, effectively eliminating air-locks that cause traditional pumps to run dry and fail.

Key Features

✔ Anti-Airlock: X-Air impeller prevents vapor lock
✔ Gasketed Lid: Seals the box against overflow and odors
✔ Tool-less Service: Snap-in pump and switch design
✔ Integral Vent: Prevents air pressure build-up
✔ Multi-Port: Connects to several drains at once

Questions & Answers

Is this a genuine original part?

Yes, this is a genuine Attwood MK2 series product, recognized for superior reliability and ignition protection in marine environments.

What is the benefit of the "Large" box vs the "Standard" box?

The Large box has a higher internal volume, which reduces the frequency of pump cycling and provides a buffer for high-flow fixtures like modern rainfall showers.

Can I use this with a 12V system?

No, this specific model is designed for 24V DC power systems only. Running this on 12V will result in significantly reduced flow and potential motor damage.

Note: Please verify your vessel's voltage and original footprint before purchasing. Standard and Large boxes have different mounting dimensions.
