    The ET Manager cartridge was discontinued. It was basically a buy out from another company. It was a HUGE disappointment to me. All it did was adjust the water budget of each program up or down based on the paging signal that it received every night. For it to work properly it really relied on having the correct program put into the controller initially. I had always hoped for an SMT on a cartridge type of deal for the LXM. I think it could have probably been done if they had wanted to do it. An LXMEF with stand alone, on site ET AND flow monitoring would have been a hell of a controller. The only thing that ever came close to that setup was the short lived IM Controller. I had two of them on a site and they were an interesting controller.

    Refresh our memories - how many threads per inch are the nozzles for the 1/2-inch brass impact heads? - I'm guessing 24, but I know some makes were 27tpi

    I am having someone refresh my memory. When I get the answer, I will share it and pass it off as my own.

    *cough cough* I seem to remember, yes, I know that those threads are 24 threads per inch.

    Thought so. For those in the audience wondering what's the deal with '24' and '27' - 27 tpi (threads per inch) makes for an impact head nozzle (for the 1/2 inch impacts used in residential pop-up rotors) that exactly matches a 1/8-inch (actual O.D. is .405") pipe thread - 24 tpi is a match for 3/8" UNF threads for US bolts and nuts, but since screw threads aren't produced with the same taper as pipe threads, there might have been some tooling employed that wasn't standard off-the-shelf stuff

    Boots, I know there is a nugget of really good information included in your message above, but I am having a 'half-brain' day and have missed it. Would you state it again so only half my brain is needed to understand it?

    The obvious (or not) reason for my intrusion was to point the way to obtaining a usable 3/16" nozzle for the guy who asked about them. He needs a 24tpi nozzle, as per your confirmation of my guess. Other brands that used a 24tpi nozzle include Nelson, which I believe were derived from Western Raintrol designs. Pretty much all ancient history by now.

    Or he could get our nozzles which a 1/32 smaller and carefully drill them out to 3/16. There is no magic other than good machining (without changing the angle of trajectory, of course).

    Of course, those brass impact head nozzles - the ones that have the diffusing screw on them - were a sumbitch to change out - I doubt anyone back then foresaw a future of interchangeable nozzles on entry-level residential rotor heads as being commonplace

    The hold-up tool was very handy.
