I have had to break out the portable for three jobs this week. Two high rise condos and once when my tm went on the fritz this morning. It is a mytee speedster 1000hv with the 200 psi option. I stupidly did not get auto-fill and auto-dump when I bought it and would like to at least add auto dump now or possibly add both auto-fill and auto-dump. Is it possible to add this stuff and if so where would I find the parts and how hard is it to do? Or do you have any other suggestions for handling the bucket brigade. I have to dump and fill after each average size room the way it is set up right now.
