Advice welcomed, have layed caravan up over winter,i am going to clean water system out over weekend with sterilising solution, but first time i have done with water heater and water filter system. can i run through without filter in situe and is it alright to run solution through water heater, but will it fill the heater first so do you have to then drain off again after sterilising. many thanks for any advice.
