If you wish to clean cladding/render/connie roofs ...you want the pump.
If you are using Quats you want a Dosatron and pump.

If you tell me what you are trying to do I can best advise...if you lads cannot make a softwash mix up manually ,the best course of action would be to change the lads.
As if they don't have the sense to mix it ...they should definitely not be applying it.

It's better not to handle hypo at all really.

Also if there is no tank there's more room.

You confuse me.
The blue framed pump has no tank.
You don't want to handle the bleach ...but you will spray it all over a customers house?
