Your site was very helpful; the photos were great and the step-by-step instructions were excellent.  I am without question an average homeowner, but I hate to call a plumber, painter, carpenter, etc.  Thanks for your help in this matter; I will be back.  Best regards to you in Alaska, Jim. These instructions were right on the money, I know nothing about plumbing but I was able to change the cylinders in my tubs easily following these instructions. THANKS! Very helpful Website. I bought the special tool to pull the valve and it came right out in two pieces. Of course, I bought the wrong replacement and had to make a second trip to Home Depot. I had a bit of a scare when I turned the main back on and the shower just dripped when the valve was opened. The sink had pressure, so I know that wasn't the problem. I pulled the shower head off and sure enough, the screen was full of junk dislodged when I changed the valve. Everything works good now. Thanks again for a very helpful website. The guys at the store didn't know diddly. I'd been putting off replacing the cartridge for months and didn't use the bathtub in fear of having a problem pulling out the cartridge. I have  hard water and it was difficult even after spraying it with vinegar. Moen never told me of the cartridge pull but your site was teriffic. I went to Home Depot and the first 2 people had no idea and the guy who supposedly knew about plumbing came over and told me he needed the cartridge, which I didn't bring because it was stuck.  After asking him about a special tool to pull it out he remembered and took me to the area with the pulls. He said he didn't have the one for Moen but I looked throught them all and found it easily. If I didn't look myself I would've had to call a plumber, and it's very expensive to have him come to just remove the cartridge. I really appreciate your site and the info you provide. Plumbing can be very tricky for a novice and since I am retired I prefer to do as much as I can, myself. Thanks again for the valuable information. Ira Your instructions gave me knowledge to try replacing the cartridge.  I was thinking I would have to have a plumber out to replace the faucet and tear out a wall to do so.   The faucet was probably installed in 1980 when the house was built.  I have several more to do now. I especially liked the info on the Brass Craft T161 tool.  That made the job very simple.  I could not figure out  what to do with the extra spacer.  I could not find a place for the ears to fit. Very informative.  While in the midst of trying to turn it bang it I decided to go online and lo and behold after 2 tries I got your website.  The pictures are an enormous help.  I might have screwed up the whole thing if I kept on.  I'll be calling a relative (plumber) to help in the removal of the cartridge as it is stuck.  Mahalo nui loa (Thank you very much) Thanks, for the help. Everything went just as you described it. The pictures and being able to enlarge them help a great deal.
