Question

The hot water tank on my 2000 dart wont fill, could this be the non return valve not working, if so where will i find it and how hard is it to replace. I get water running through the cold tap. It's a cascade 2

Answer

It sounds as if the non-return valve is stuck. This is situated at the inlet of the heater (bottom right when looking at the rear of the heater). The plastic inlet connection should be removed and if you require a replacement it is our part 128606.
