Both have the potential to flood the caravan with unlimited volumes of water for which equally effective safeguards against flooding are easily to hand for when the caravan is unattended. .. These days, combi heating systems are most popular, and they are efficient, heating both the water and the internal space (hence the name) throughout the caravan.

An alternative is to use a pressure reducing adaptor that can connect between the high pressure supply tap, directly into the caravan inlet. This does away with the need for both the external water container and electric caravan pump, relying instead upon the on board caravan taps to stop water flow. Unfortunately these systems are more expensive and are more prone to leak.Through lifting the diaphragm up and down, suction is created along with positive pressure on the outlet. Remember, at least once every season, you should be sterilising the water system in your caravan or motorhome. So, you base your decision on how perfectly the pressure reducer will always operate, and on never getting anything from the water supply or your hose into the valve.

Yes, you can continue to return items as normal as long as you follow the government guidelines about leaving your house. The two main brands of submersible water pumps used on caravans are Truma and Whale. These two brands of submersible water pumps are very similar when it comes to flow rate and pressure.

How a diaphragm water pump works is the motor lifts a piston up and down, which is attached to a rubber diaphragm. The scenario you describe where regardless of the source of the water the caravan floods is indicative of faulty pipework in the caravan and not of the difference between a pressure reducer or a floatation valve in a water barrel, and both would have the same outcome. Sometimes the issue with a tap not working in a caravan or motorhome is due to the tap itself (microswitch), which I’ll discuss below. If you have reviewed all of the information above and tried the various solutions to no avail, your service centre is going to have to help you to get the tap working again.

Therefore its a wise investment to have a quality leisure battery charger to keep your battery healthy. Whether the water is delivered straight to the inlet port on the side of the caravan or continuously to an aquaroll with a pressure switched pump, both depend entirely on the integrity of the internal plumbing. I cut the tube to a suitable length. (I actually made two filler tubes one at 500mm and one at 700mm.) Systems vary between van brands, but the logic is usually similar. Many feature a selector switch, which changes the water source from an external one (Aquaroll/Waterhog) to the internal fresh-water tank.This will increase your fuel consumption and might affect handling, especially if it is located towards the rear of the caravan, where the ‘pendulum effect’ is most potent. Some luxury caravans have an onboard water tank, which needs to be filled with clean water. Depending on the size of the vehicle, these vary from around 40 litres upwards. A submersible or on-board diaphragm pump can potentially be damaged by running dry, hence with no water supply. Not much to add about the Aquaroll to what is already known- it is tried, tested and lasts. If there are any more than 2 people in your party, you want to get the 45L rather than the 29L one or you will be spending more time than planned at the water tap refilling, no fun in recent weather.

If your caravan or motorhome taps operate using a smart switch, its generally located centrally in the caravan, typically under the seats: Image – Truma.com Alde wet systems are rather different. Where Truma and Whale use hot air to heat the vehicle, Alde uses a domestic-style radiator set-up – pumping hot liquid around the caravan to radiator panels that are hidden behind the furniture. Control panel for Alde heating system Most will be filled from an external water-carrier through a second port on the side of the caravan. Others are like some motorhomes, and can be filled with a hosepipe, through a filler cap on the side of the vehicle. External water supply connection ports on the caravan sidewall Whale has tested its system and found it can heat enough water for a 14-litre shower in 11 minutes, and then takes only a further eight minutes to provide the water for a second hot shower. If you account for drying-off time, Whale Expanse delivers consecutive showers with virtually no waiting time.

Touring Caravanning

Hence the pipe exits the caravan and has to loop up and then down to get into the Aquaroll. This then creates a kink in the pipe. Hence the pump cannot pull water through the pipe. Furthermore, depending on how much debris and particles there are in the base of your Aquaroll, the filter may require more frequent cleaning. By comparison, the pressure reducing valves connect directly to the caravan, and if they begin to leak internally then as has been stated already that will allow the static head pressure of the mains water to be applied to the caravans pipe work. If the various Pressure Relief Valves (PRV's) normally associated with water heaters, but in teh event of a catastrophic Pressure reduction valve failure its would likely exceed the flow capacity of the PRV's and pressure in teh water system could build up to dangerous levels beyond the pressure rating of the appliance's and fittings.
