I would appreciate any suggestions on where to purchase a good chemical injector for down streaming . right now I have a 12 to 1 .I am looking for something with more draw for cleaning power.THANK YOU!

Downstream chemical injectors are super-sensitive to “flow-restriction”..

rusty fittings, especially rusty hose-ends are really bad.

The heater iis flow restriction, Lots of hose on a reel is,

The reel swivel is a flow restrictor too.

Installing your injector of choice at the inlet of the hose reel would work fine, BUT..

Do it on a quick coupler, so you can remove it when you don’t need it.

Or, use the ST61 injector.. it’s the one -size- fits –all (from 2 to about 8gpm),

It is adjustable for system-flow, and you can open up the venturi

to NOT restrict flow when you don’t need chemical,

and they work at any flow-rate, with any hose length, before, or after your heater.

They are very easy to adjust, and you can leave it on, if you like.

I think DEMA will have larger ones too, but the ST series is VERY affordable.

Call one of the parts dealers about that. :)

I use a super suds sucker from envirospec. It has replaceable orifices inside that you can change out to fine tune it to your setup. I also have a 2gpm delavan pump that feeds my injector so that I get the same draw rate no matter how much hose I have hooked up. I've had 1000' of hose on it and still get over 30% draw rate.
