Caravan Water Pressure Regulators and Valves That Keep Flow Under Control
Enjoy steady water flow with a caravan water pressure regulator built for Australian conditions. Mains pressure at parks can surge and throw your setup out of balance. A good valve keeps things smooth and helps your pump and hot water system run the way they should.
Why You Need a Water Pressure Regulator for Your Caravan
Not all caravan plumbing is made to handle full mains pressure. In some parks, water pressure can hit 2000kPa, while most vans are only rated for around 350kPa. That’s a big difference.
A caravan water pressure regulator brings that pressure down to a level your system can handle. It helps your hot water system, like a Truma or Suburban, run smooth and steady. It also keeps things balanced when you hook up at parks, so your taps don’t surge or sputter.
What to Look For in a Caravan Water Pressure Regulator
Preset Pressure Rating
Most caravan water pressure regulators drop mains pressure to around 350kPa or 50 to 65 PSI. That’s the sweet spot for keeping your system running smooth without putting strain on your plumbing or hot water unit.
Check Valves
Many models come with a built-in valve to stop backflow. This stops mains water from pushing back into your tank and keeps your lines flowing one way.
Mounting Style
You’ve got options to match your setup. Go for a wall-mounted unit for clean installs, a brass inline valve for fixed plumbing, or a quick-fit kit for hose connections.
Thread Types
Most caravan setups use BSP or NPT threads. You’ll find 12mm and 15mm fittings to suit common hoses and pipework in Aussie vans and campers.
More than just caravan water pressure regulators and valves
Building out your water system? These extras help you get the most out of your setup:
- Caravan Water Tanks – Store fresh water on the road with tanks built for rough tracks
- 12V and 24V Water Pumps – Keep water moving to your sink, shower, or tap
- Hoses and Piping – Set up flexible lines for filling, draining, or connecting to mains
- Water Filters – Block out grit and sediment to protect your pump and pipes
These parts work together to give you reliable water flow anywhere you park.
Common questions about caravan water pressure regulators
What’s the difference between a valve and a regulator?
A valve controls the direction or flow of water. A regulator is a type of valve that reduces pressure to a set level. Some pressure regulators include a check valve inside to stop water flowing backwards. You’ll often see both terms used together in caravan plumbing.
What happens if you don’t have a pressure regulator?
If you hook up to mains without a pressure regulator, you risk high water pressure flooding your pipes. This can damage your (hot) water system, crack fittings, or cause leaks. Most caravan plumbing is only rated for around 350kPa, but some parks supply water at over 2000kPa.
How often do you need to replace a water pressure regulator?
Most good-quality regulators last for years. You don’t need to replace them often unless they start leaking or the pressure drops off. If you travel full time or often hook up to mains, check your regulator each season to make sure it’s still working right.
