One of the first questions when customers call to enquire about a service is what do we actually do during the process. What are the things we check. Read on to find out about the main points covered during a normal NCC Approved Caravan Service.

Caravan Chassis Check
The main points checked in this part of the service are the caravans brakes and running gear.
Essentially everything you rely on to get your caravan safely to your holiday destination. The caravan corner steadies are greased and checked to make sure they are not distorted at all and raise and lower freely. We check the overrun to make sure the damper is working correctly and preventing your caravan from crashing into the back of the car under braking. This item is essential to make sure the brakes are being applied smoothly when on the road. We check to make sure the stabiliser pads in the hitch are working correctly, are adjusted properly and are clean and free from grease and dirt to ensure they grip the tow bar and stabilise the caravan correctly during the journey. We then raise the caravan and remove the wheels. Tyres are checked to make sure they are not cracked, are within the manufacturers recommended age, the tread is above the legal wear limit and there are no signs of damage that may cause a problem on the road and then ensure they are pumped up to the correct tyre pressure. After the tyres have been checked the hubs are dismantled in order to check the brakes and wheel bearings. All parts are cleaned and copper ease applied to moving parts as necessary before reassembling using new one shot hub nuts tightened to the correct torque setting. The brakes are then adjusted to make sure they do not bind before the wheels are replaced and torqued to the correct manufacturer setting.
The final element of the chassis portion is to check the road lights. This also includes ensuring the connection to the fridge on 12v is working as it should to keep your fridge cool during the journey and if installed the electronic stabiliser is activating as it should.
Caravan Gas Service
As everyone know a poorly maintain gas system in a caravan can have catastrophic consequences. The tests we carry out as Acops certified engineers are in line with gas current regulations for gas installations. A copy of the certificate can be found by clicking here. We first of all ensure the gas system is sound by checking for leaks. This is done by using a manometer to measure pressure drops over a prescribed time period. Once we are happy there are no leaks present in the gas system we move on to checking the appliances are working correctly. we switch all appliances on and make sure they ignite, that they stay lit and the flame pattern is good showing that there are no increased levels of carbon monoxide being produced. once we are happy that the appliances are working well we move on to testing the flame failure devices built in to each appliance. This is a safety feature that ensures the gas valve closes automatically should the flame go out unintentionally. This completes the safety check of the gas system however we check to make sure gas drop holes and vents built in to the caravan are clear of obstruction so that in the event of a leak the gas has a means of escape and does not build up inside the caravan potentially causing a fire.
Electrics within a caravan consist of both a 12 volt system and a 240 volts mains electric system. Plug sockets, space heater, water, heater, the fridge and battery charger run off of mains electric and pretty much everything else works on 12v. Mains power charges the battery and the battery provides the power for the appliances. During a service we check each of the appliances individually and make a visual check of any wiring that is visible to ensure that it is correct, fit for purpose, has no damage and connections are not shown signs of corrosion that could lead to short circuits or worse: fires! We check power sockets to makes sure they are wired correctly and working properly and check the current draw on all appliances to ensure they are not failing. A 1000 watt heater for example should draw in the region of 4 amps (most sites power is rated at 16 amps). if we do not see 4 amps when testing then we would have concerns that something is not right and advise the customers accordingly. it could be an element is failing or a circuit is somehow disrupted and the correct power is no getting through; all advance signs that something is not right. We check bonding to chassis and gas pipes to ensure all appliances are correctly earthed and finally we do a test of the RCD by simulating a fault in teh system with a RCD tester to ensure it trips properly within the timescales set out in the industry guidance.
