Prier 630-7755 Wall Hydrant Repair Kit

This kit provides parts for fixing several models of Mansfield/Prier hydrant. The parts are relatively easy to install, but finding the right parts to use from the package, as well as the orientation of the basket washer for my 500 series, proved to be less than intuitive. My first mistake was removing the entire hydrant from out of the wall (my initial thought was that I would have to get a new one). THEN I found this kit, which can be installed without removing the hydrant (ha-ha). The parts diagram on the back of the package is pretty much useless. I went to the Prier website and found a PDF of the assembly that helped a bit. I finally noticed that on the bottom of the parts diagram on the package is a general reference to YouTube. I went there and searched for "Prier" and quickly found a video that covered my 500 series hydrant. Wish I had looked there first. As others have noted, this kit does not have any repair parts for the vacuum assembly -- there is a separate kit for that (630-7500 for the 400 and 500 series), as well as another YouTube video. Overall, things will go a lot easier for you if you watch the YouTube videos first. Good luck!

I bought this for an external hose bib at my hunting cabin. I have no idea how old the original was, but it was very hard and no longer would seal without dripping. I installed the new seal on the end of the rod and replaced the collar bushing. It works like a charm now, and requires only minimal force to make a leak free seal. When installing the new bushing, just be careful not to chip or damage it when inserting. The new bushing also stops the squeaking. This is an easy fix to an annoying problem. I recommend it.

UPDATE May 2020- last year I replaced this and was delighted. Just turned water back on for the season and leaking again!!! This should not be a repair that needs to be done every year! Now very disappointed - back to you tube to see if the rod itself could be part of the problem. This worked perfectly, and I only looked at this option after realizing that replacing the entire frost free assembly couldn’t be done due to lack of access from the basement. This kit has everything you need plus more, which is a bit of an issue. There are a lot of extra parts so determining which washers and seals to use was more difficult than it should have been since you tube video did not show up close parts view. YOU MUST DETERMINE 100% the make and model you are replacing to make sure this is the kit for you, ( mine was a Mansfield 300 ). Once you do however this has everything you need to fix the leaking spigot (unless your handle needs to be replaced too - that you will have to order separately.) Great fix and low price!

My outside hose bib (spigot) would dribble out of the on/off handle, so I couldn't leave it on for any period of time. A little research to figure out what my spigot was (old style Mansfield 500 w/ left handed threads) led me to this kit. All I did was look up the stem parts breakdown and replaced all of the washers and parts I could. Re-assemble, and turn my water back on, voila! No dripping at all. Included several parts I didn't need (if you can consider that a knock). I know the kit covers a couple of other stem types, but it did add a little confusion as to what parts to use.

The kit does all 300 400 500 600 Mansfield (now Prier) faucet stem washers and packing. It has packing materials for both the left hand and right hand packing types. For me this is a 300 series (RH) and a 500 series (LH). Though I needed the kit for a second faucet it would have been better if I had removed the stems for inspection before I ordered the kit. In my case one of the washer retaining screws in the end of the model 300 stem had rotted out so badly I could not get the remnants out of the stem and had to order a new stem which comes with washers and packing. The other thing I learned is that the vacuum break can also leak. Those parts are not in this kit. So if you have a vacuum break check if it leaks before ordering parts. There is a kit that includes the vacuum break components as well as the stem washers and packing. Fortunately there is also a kit that only contains the vacuum break components so I didn't lose much by not ordering everything at once. Mansfieldparts has a great short video on how to tell the different models apart and shows you the relevant part numbers for each unit. If I had a leak in a faucet with the vacuum break I would just buy the all inclusive kit and change all the washers and packing at the same time. It is quick and easy. Overall I like the quality of the kit. Jay

Our 400 Series Anti-Siphon Wall Hydrant was dripping from the outlet. I looked at several of the on-line Prier videos before starting the repair. When I removed the stem, the rubber boot was torn up and loose on the stem. It took me a while to figure out that the rubber boot was the anti-siphon part of the assembly and that it had to be stretched over a raised lip just below the threaded end of the stem. Once I did that, completing the repair was easy. No drips! This repair kit had all the parts necessary to stop the leak.

I recognize that it's not sold as a universal kit, but I bought it hoping there might be comonality of parts enough that I could use it for another brand. It doesn't have any of the parts needed to fix my wall hydrant. Be sure you have a Prier faucet and don't think you'll be able to get this to work for all the others. I realize this is as much my fault as anything else, so I didn't take off a bunch of stars for it - more a warning for anyone else. The parts seem to be well enough made, but not great. The seals are thin, the threads sharp - overall, the quality is probably good enough to get your Prier faucet fixed, but isn't going to be the end-all solution.

Seemed to work just right. No more drips. Just a warning that you’ll probably have to wrestle with some stuck fasteners to make the repair. The videos on how to do this work is helpful, but they show it using a new hydrant—in reality you’re buying this for an older unit, meaning the handle bolt and stem screw are stuck. I used a strap wrench and socket to gently remove the handle bolt, and had to destroy the old washer so I could grab the stem screw with a pair of channel locks. And lots of penetrating oil.
