Caravan Plumbing & Water Systems
Caravan Plumbing and Water Systems
A reliable water system is one of those things you quickly notice when something isn't working properly. From getting water to the kitchen tap and shower to keeping track of what's left in the tank, each part of the system has its own job.
12V Caravan Water Pumps
A 12V caravan water pump moves water from your onboard tank through to your taps, shower and other outlets. If you're replacing an existing pump, check the old pump first rather than choosing a new one on size or appearance alone.
Important things to compare include voltage, flow rate in litres per minute, pressure in PSI, inlet and outlet fittings, current requirements and the space available for installation.
Caravan Water Tank Monitoring
Water level indicators and sender probes help you keep an eye on the water stored in your caravan tanks. This can be particularly handy when you're free camping or travelling away from a mains water connection and need to manage your water use.
Water Filters and Plumbing Accessories
Filters and other plumbing accessories can help keep a caravan water system working properly. Always check the required fittings and compatibility with your existing plumbing before ordering.
Caravan Showers and Bathroom Accessories
Caravan bathrooms need to make good use of limited space. External showers and other compact bathroom accessories can provide practical options for touring, camping and everyday use around the van.
Choosing a Caravan Water Pump
Choosing the Right Caravan Water Pump
If you're replacing a caravan water pump, start by checking the label on the pump already fitted to your van. Matching the existing system is usually a better starting point than simply choosing the pump with the highest flow or pressure rating.
| What to Check | Why It Matters |
|---|---|
| Voltage | The pump needs to suit your caravan's electrical system. Many caravan water pumps operate on 12V. |
| Flow Rate | Measured in litres per minute (LPM), this tells you how much water the pump can move. |
| Pressure | Measured in PSI. The pressure needs to suit your caravan plumbing, fittings and appliances. |
| Fittings | Check the inlet and outlet connections against your existing plumbing. |
| Physical Size | Make sure the pump and fittings will fit in the available installation space. |
| Water Demand | Consider the taps, shower and other outlets the pump needs to supply. |
More flow or pressure isn't automatically better. A pump needs to suit the plumbing system it's connected to. If you're replacing an existing pump that performed well, matching its main specifications is usually a sensible place to start.
What to Check Before Ordering
What to Check Before Buying Caravan Plumbing Parts
Caravan plumbing components can look similar while having different specifications and connections. A few checks before ordering can save a lot of trouble during installation.
Check the Existing Part
If you're replacing a pump, sender, filter or another plumbing component, check the existing unit for a model number, voltage, measurements and connection details.
Check Your Fittings
Different caravan plumbing systems can use different hose sizes, threads and fittings. Compare the connections shown on the product page with your existing setup.
Check Water Pump Flow and Pressure
When replacing a water pump, compare both the flow rate and pressure with your existing pump and plumbing system. Don't assume a higher number is automatically an upgrade.
Check Electrical Requirements
For 12V pumps, water level equipment and other powered products, check the voltage, current requirements and wiring instructions before installation.
Check Tank Equipment Carefully
Water level senders and monitoring equipment need to suit the tank and monitoring setup they're being connected to. Check probe length, wiring and compatibility before ordering.
Use a Professional Where Needed
If you're unsure about plumbing connections, electrical wiring or modifying your caravan's water system, have the work carried out by a suitably qualified professional.
Caravan Plumbing FAQs
Caravan Plumbing & Water System FAQs
What size water pump do I need for my caravan?
There isn't one pump size that suits every caravan. Check the voltage, flow rate, pressure, fittings and water demand of your existing system. If you're replacing a pump that worked well, its specifications are a useful starting point.
Are caravan water pumps 12V?
Many caravan water pumps use 12V power because they're designed to operate from the caravan electrical system, including when you're away from mains power. Other voltages do exist, so always check before ordering.
Is a higher PSI caravan water pump better?
Not necessarily. The pressure needs to suit the caravan's plumbing, fittings and appliances. Fitting a pump with considerably higher pressure than the system is designed for can cause problems.
What does LPM mean on a caravan water pump?
LPM means litres per minute and describes the pump's flow rate. It gives you an indication of how much water the pump can move under its rated conditions.
How do I know how much water is left in my caravan tank?
A compatible water level monitoring system uses a sender or probe to help indicate the amount of water remaining in the tank. The exact setup depends on the tank and monitoring equipment fitted to your caravan.
Do caravan water pumps need a filter?
A suitable filter or strainer can help stop debris from reaching the pump. Whether one is required and where it should be installed depends on the pump and plumbing setup, so follow the manufacturer's instructions.
Can I replace my caravan water pump myself?
That depends on your experience and the installation. The replacement needs the correct plumbing connections and electrical wiring. If you're not confident working with either, have it installed by a suitably qualified person.
What should I check before buying caravan plumbing accessories?
Check measurements, connection sizes, voltage where applicable, product compatibility and the specifications of the part already fitted to your caravan. Don't rely on appearance alone.
