Planning your RV or motorhome water system can be tricky with so many pumps, tanks, and accessories available. This guide walks you through everything you need to know to choose the right components for your vehicle, from water pumps and waste management solutions to accumulator tanks, booster sets, and heater pumps. We’ll also cover the essential extras like filters, strainers, and pressure regulators, helping you create a reliable and efficient water system for your adventures on the road.
Outfitting your RV or motorhome with the right pumps ensures reliable water delivery for showers, taps, and onboard appliances. This guide breaks down the main pump types, their key differences, and the essential accessories you may need.
Water pumps are the heart of any RV or motorhome freshwater system. When choosing the right pump, consider the following:
Flow rate determines how much water the pump can deliver per minute. Larger motorhomes with multiple taps, showers, or appliances need higher LPM (litres per minute).
Automatic pressure switches start and stop the pump depending on tap use, maintaining consistent pressure and protecting the pump from overuse.
Most RV water pumps run on 12V or 24V DC, powered by your vehicle battery. Some pumps can also run on AC when connected to campsite mains electricity.
Choose a pump that can handle the number of taps, showers, or appliances used at the same time. Larger RVs need higher-capacity water pumps to maintain pressure across multiple outlets, while smaller campers can use lower-output pumps.
Jabsco / Flojet have the Triplex and Parmax Series water pumps, as well as the LFP Series for smaller applications.

Macerator and waste pumps are essential for handling grey water and black water in your RV or motorhome. The type of pump you need depends on how your onboard waste system is configured:
Standard waste pumps move grey water or black water from your holding tanks to a dump station or outlet. They are best suited to systems where large-diameter hoses and gravity drainage can be used.
Macerator pumps grind waste into a fine slurry, allowing it to be pumped through smaller diameter hoses, ideal for compact plumbing layouts or when you need to transfer waste through a garden hose to a portable tank or discharge point.
Jabsco have a series of waste pumps, and for macerators we recommend the Flojet Macerators.

Accumulator tanks help smooth out water flow and reduce pump cycling in your RV or motorhome. They store a small volume of pressurised water, maintaining consistent pressure at taps and showers and extending the life of your pump.
The Jabsco Accumulator Tanks are ideal for small to medium RV water systems. They reduce pump cycling, maintain steady pressure, and improve system performance.
