This is a simple procedure – fill the tank or plug in your water source (a water-carrier or waterline), then, with each hot-water tap open in turn (or mixer taps switched to the hot setting), turn on the water pump. The heater holds up to 15 litres of water, so might take a minute or so to fill.The Thetford Porta Potti 565p offers a comfortable, home-like toilet shape that doesn’t need a drainage connection. This portable toilet has an integrated flush water tank and waste holding tank, making it easy to transport. With its comfortable seating height and bigger toilet bowl, this design is the next best thing to your toilet at home. Waste and water products from Halfords The method of emptying the tank varies from caravan to caravan. Most vans drain down via a small inline valve located close to the heating system. A few tanks sit under a hatch in the floor. With these, you’ll often find a handle and pull-cord, which, when tugged, opens a valve and drains the tank. Other vehicles have an external drain tap, which sits under the edge of the caravan. 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. ..

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. However, you shouldn’t worry about dry running for short periods of time. For instance, with a submersible pump when the Aquaroll is empty.

Water is pumped in at one end, through the heating system and over the heat-exchanger fins, then out of the other end to your tap, when the required temperature is achieved. Hot water systems

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. Yes, you will be running the pump for a short period of time just as the water cylinder becomes empty, but that’s unlikely to lead to damage. While this might not save a lot of effort, having a secondary water tank can mean that one ‘water-filling’ session will last you the whole day, or perhaps even a weekend if you’re frugal. There are two main types of water pumps. Submersibles, which actually go into your Aquaroll water container, and onboard diaphragm water pumps. Submersible Water PumpsHeat exchangers used to have a 10-year lifespan. Brands like Truma have extended this to 30 years, but since June 2005, any heater with an E1 mark on its type plate (European Directive approval) no longer has a specified lifetime.
