HELP: plumbing question for delevan pump

[Off D Wall]

I got a 200gal tank that i have been using to p/w on job that water was not available.
I am instaling delevan 5800 series pump for roof cleaning and thinking of dedicating this tank for the apple sauce.

right now my plumbing is set whit a 2way T ball valve ,got 4ft poly hose on one side to rinse my hand if needed ,and other side got h2o suply hose to p/w whit a quick connect for easy switch from customer h2o or from tank .

QUESTION
SHOULD I PUMP MY SAUCE FROM EXISTING SET-UP BY JUST ADDING A Q/C FEMALE @ PUMP INLET OR DRILL HOLE ON TOP OF TANK AND INSTALL PIPE AND PUMP FROM THE TOP???????

I WILL WAIT TO HEAR FROM YOU GUYS BEFORE I START DRILLING HOLES..

My opinion is to get another tank just for chlorine.

It seems like a mighty big tank just dedicated to roof cleaning, I only use about 50 to 60 gls on a roof.If you have the room on your rig go for it if not get a smaller tank for the sauce.

If you do use it I like the pipe from the top instead of the side.

We use a 55 gal plastic barrel and pull from the top. Any fittings or bulkheads will eventually leak, and that can get ugly in a hurry.
