    Unusually water leak on a Worcester Greenstar 25cdi boiler. The plastic section behind the dhw temperature sensor has developed a slow leak.

    Hi As you can see on the attached picture a slow leak has developed on this large plastic piece. I am trying to find out is the leak is fixable and if so with what? If the leak cannot be fixed can that whole plastic section be purchased as a replacement part?
