Frequently Asked Questions - Water Pumps

How to choose a caravan pump

The best caravan pump is one that will operate quietly and with no fuss for many years. Your caravan pump will be able to handle pumping a small amount of water at the kitchen sink or basin, or able to handle one or two taps (shower and sink) operating at the same time without making the person in the shower scream because the water has gone cold!

Everyone has a different budget and caravan size to work with when purchasing and there are a huge variety of caravan pumps available for every budget and every set-up. Water Pumps Now has a large range of quality affordable caravan pumps to make sure we have a caravan pump to suit you.

To pick your pump you need to know whether you require a 12 volt or 24 volt caravan pump and how many taps you want to run in your camper-trailer, caravan, RV or bus.

The best caravan pump is not the biggest pump you can buy. Always buy the correct pump size to suit your van. 60PSI is normally too high a pressure for a caravan unless it has 5 to 6 outlets.Caravan food van water pump setup 2

Single Tap

If there is only one tap/outlet in your camper-trailer or caravan (say the kitchen sink) then you will only require a caravan pump which will deliver what you kitchen tap would use at full flow. If your tap flows up to 5 L/min then the best caravan pump is one which will deliver this amount over the one minute.

Two Taps

If you have two outlets in your caravan, say a sink and a shower, the best caravan pump for your setup is the one which can deliver enough water flow to both outlets if they are in use at the same time. This is determined by how many litres per minute each of your outlet delivers. Add the two amounts up and purchase a pump which will deliver the required amount. Typically a pump delivering around 9 to 12 L/min will suit best.

Three Taps

If you have 3 outlets in your caravan you will require your caravan pump to deliver around 12 L/min in case all outlets are in use at the same time. Typically you may have someone in the shower whilst someone else uses the kitchen sink.

Four Taps

A four tap/outlet caravan, bus or RV usually will have a toilet, shower, vanity basin and kitchen sink. Typically the best caravan pump for your set up is one which will deliver up to 17 L/min if a number of these outlets are being used at once.

Five taps

A five tap setup will usually have a washing machine together with a sink, basin, toilet and shower. In order to run a number of these outlets at the one time you will require your caravan pump to deliver up to 22 L/min.

Matching your pump to your Gas Hot Water Heater

If you have a gas hot water system, please check the specifications on what PSI is required to ignite the pilot light so the gas hot water system will operate. If the gas hot water specifications use the term "Bar" then 1 Bar = 14.5 PSI or "KPa"  then 6.89 KPa = 1 PSI.

Escaping Outdoors FL Pumps

The cheapest alternative is the Escaping Outdoors FL diaphragm pressure pump range. They are an excellent caravan pump, widely used throughout Australia for over 15 years and will last for years and years using both salt and freshwater. They do not have a return valve or built in bypass so you will need to match your caravan pump to your system a little more closely and add a small pressure tank (accumulator tank) if required to balance your water flow (the pressure PSI) in your system. An accumulator tank provides a constant and consistant water flow and reduces water hammering and cycling. Escaping Outdoors pumps come with a 12 month Australian Warranty with spare parts and technical help available 7 days a week.

Jabsco ParMax Pumps

The Jabsco Parmax range of pumps are marine grade and can be used in either caravans or boats. The built in bypass in these caravan and marine water pumps lowers pulsation and noise and there is no need for an accumulator tank in most systems, however if you have constant water hammering or cycling in your system, Jabsco also recommend an accumulator tank to minimise and alleviate this issue. Jabsco caravan pumps are available in 12V and 24V water pumps with a 3 year manufacturers warranty.Jabsco ParMax 4.3 12V marine grade freshwater pressure pump 1
