Hi We have a 180 6 berth and was wondering how to protect the separate Thetford toilet cistern (ie has its own reservoir not from the main tank. Is there any way of draining this type of cistern. Book suggests putting antifree in the tank (non Toxic Glycol type) is this the same type has used in the car.
Also is the boiler simply drained down from the waste water tap or does it have it's dedicated drain outlet
