Are you using the new wrench to remove the old sprinklers? If so that could account for the premature wear, I've seen old sprinklers that seemed like they were welded into the fittings. Since your replacing the sprinklers and since by the standard you can't reuse the old ones, just use an adjustable wrench. Or measure across the flats and use an open end metric or SAE wrench that is close the right size. Most of the sprinkler we deal with fall between 3/4" and 7/8".

So I ordered the specified wrench, so we could change heads w/o damage to the new heads. My guys changed 6 heads before the wrench wore out. We have had the same problem with all the brands. What is the solution? The last wrench cost me $150.00, that is an additional cost of $25.00 per head. I have been thinking of having the welding shop build up the wrench with hard face powder and then having the machine shop mill the wrench to the right size. Any other options? _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org
