Just had our first run to the coast in our "new" T25 and what a great day we've had

A couple of issues arose during the day!! I filled the water tank up this morning so we had some water on board to boil etc but as soon as i did found the floor flooding!! I found that the small double sided "in" "out" cream coloured filter connecting the water tubes from the tank to the tap had basically perished.. so my question is.. where can i get a new one from???? any tips would be greatly received..
The second and more worrying thing was that once we'd reached our destination and stopped her.. water came pumping out of the radiator.... as if she'd overheated, but the temp gauge didn't show any problems and as soon as she cooled down she was fine.. we drove her home no problem... and as soon as we parked up outside the same problem!! water gushing out for a few minutes then stops!! any ideas???
Apart from that we had a wonderful maiden voyage in our T25... here's to many more!
Thanks for any help you guys can offer!
