No probs. It's certainly not the most productive set up by any means compared to what you can get but is cheap and will pay for itself on day one any many more times over.
I found it was best to add a wfp pump controller to it so you can adjust the flow for the job in hand. That way you have full control so to help reduce run off, chem drift and chem wastage.
.
I'm sharing the pump controller with my wfp pump, using a switch
Then I used a couple of T connectors and some valves so that I can switch from ddac (that's in the small tank it came with) to pure water from my main 650L wfp tank, so that I can flush the system after using it. and also acts as a 3rd reel if I get desperate lol.
I was thinking of getting another tank for the SH with another T connector and valve, then switch to whatever I want.
I need to think about rinsing now and I'm currently waiting for Ben to reply with his recommendation. Was thinking maybe of getting a high pressure washer for rinsing, which I could then use for paths and driveways.
