Been reading up on the new R4045 and one thing I like is the air forcing the chem out of the line when cleaning. Has anyone fitted something similar to a 4940. It won't be as flash as the inbuilt of the 4045 but will still do the job. Or are there other ways less complicated to clean the boom out?
Wilger also makes a half turn flush valve on the end of the boom. Threads onto a 1" NPT. Run about $25 per valve. Pretty compact and just a bit cleaner than having a ball valve off the boom (fits tighter into the boom as well)
