Just went through the process today of cleaning Valor out of aur 4720 sprayer. Finnally found some of the Valor tank cleaner. Only one dealer had ever heard of it. Why? I think you should provide it with the puchase. I broke every line and diaphram and hand cleaned them. I will say the tank cleaner is GREAT. As far as not being able to drain the tank I have no problem getting this done. I have ran a lot of different sprayers in my day and have never had one set up to drain the tank without it going through the pump.

We like the control we get with the Valor but this problem of having it hang up in hoses and tanks is not very pleasing. Now that we found this tank cleaner maybe this will conclude our problems.
