Im sure someone on here said a while back that orion pro should be able to take hot water.
I have now been through 3 pump o-rings. They last for a few jobs and then begin to disintegrate, seazing the pump up.
It has only started happening since I started using hot water for pre-spray (tap hot)
Cleansmart said that this is a normal problem - orion can not take heat.
Is there a way round this? The rubber o-rings are very expensive at £7ish a pop if I remember rightly.
