In response to Re: Mansfield Outdoor Faucet (Anti Siphon) Leak
Mansfield puts out two kits, one #630-7500 to repair the anti-syphon valve, for around $3.00 and the other #630-7755 to rebuild the rest of seals and washer for around $7.00. They should be available at most plumbing supply houses, etc.

Many times a quick repair for the anti-syphon is to pry off the plastic cap with a screw driver, being careful not to break it. Work a little from two sides until it pops off. You can then unscrew, counter clockwise, the bonnet (valve retainer) with a pair of plyers. Clean any crud from under the bonnet, which acts like a washer seat. You will find a plunger assembly, clean and reverse the washer in the assembly. Re-assemble the parts you just removed. Tighten the bonnet firmly. Snap the cap back on. With a little of luck you will get many years of additional service before needing a repair kit.

: I know that this subject has been touched upon in the past, but for those that have dealt with mansfield wall hydrants, any recommendations on how to remove that assembly under the anti-siphon cap? It's made of plastic and appears to be screwed in, but only has tiny little plastic teeth that I've found very hard to grip.

: Any help for this rookie plumber would be greatly appreciated. Thanks in advance
