Motorhome, caravan or horsebox been parked up for the winter???? Have a read:-
The waste tank
When a motorhome is laid up for long periods (especially during the winter), the blade of the waste tank should be left slightly open so that it does not stick to the lipseal. However, many people forget to do this and leave the blade in the closed position. This can also result in the lipseal being damaged if residual water between the two elements freezes.
Having removed the waste tank, spray a small amount of Thetford Maintenance lubricant on the blade and lipseal and carefully open and close the blade a few times. Close the blade and then check that there has been no damage by pouring a little water onto its surface. If all is as it should be, the water should remain and not drip down into the waste chamber. If there is a leak, you will need to replace the lipseal. Once you’re satisfied there are no leak between the lipseal and the blade, you can charge the waste chamber.
Toilet freshwater tank
If you’ve left water in the fresh-water chamber of the toilet, you should now top it up and flush it through the system, as there will almost certainly be some algae in the tank – easily recognised as black streaks in the water. It may be necessary to fill and flush more than once before the water is clean. Once you have got rid of all the algae, charge the tank, adding some Thetford Aqua Rinse in correct proportion to keep the water fresh.
