If it needs to be replaced then do that you might have to go to home depot to find out what you need to solve the water pressure problem usually the valves in the pipes could be an issue hopefully it's not something the plumber has to get involved with that can be pricey but call or visit your local Home Depot store so they can be better to assist you.

SOURCE: moen posi-temp for shower pressure

There is a little "o" ring in the shower inlet that is designed to collapse as the pressure increases, limiting flow. You can safely remove this and then have un restricted flow.

SOURCE: how remove the broken bathtub cartridge(Moen 1222)

The exact procedure to remove the old cartridge is with a plastic removal tool.With replacement cartridge you have to buy this plastic removal tool.Also there is same metal removal tool available.With the help of this tool you can easily remove the old cartridge.
Moen Cartridge Replacement Instructions

Moen shower faucet cartridge replacement is a project that will take some time to get done right. When is it time to replace a Moen cartridge? If you are like most people, you won't want to replace your old Moen cartridge until your old cartridge is starting to show its age.

Replacement is necessary, usually, once the old faucet starts to drip. Thankfully Moen faucet cartridge replacement is not difficult. However, if you are uncomfortable with doing the repair yourself, do not hesitate to call a professional plumber to do the job for you. This will guarantee that the job is done right.

If you follow these Moen faucet cartridge replacement instructions you will be able to replace your old cartridge by yourself. First of all, as with any plumbing repair, make sure that the water supply is turned off. Open the faucet to remove water pressure from the lines and let the remaining water drain from the pipes. You will then need to remove the faucet's handle by removing the decorative cover and removing the retaining screw. This will allow you to remove the handle.

Once the handle has been removed, work on releasing the splash plate from the wall. Generally there will be one or two screws to remove and the plate should release from the wall easily. From here the process begins to get a little trickier. Insert a shower stem socket onto the faucet valve's retaining nut and release the nut. Your Moen cartridge removal will be complete once you grab the cartridge with a pair of pliers and pull straight out to remove the old cartridge.

Clean any surfaces that you have access to and replace with the new cartridge. Follow all of the previous instructions in reverse order to re-assemble your shower faucet. Check to make sure that all the connections are tight before turning the water back on and testing the system out.
Now in your case the broken/cracked while removing the old cartridge so try this procedure carefully to get the stuck -up old cartridge out.
TAPPING the Threads into the Cartridge:
Carefully  hold one tab on the cartridge tight against the brass lip on the faucet body with needle nose and try  to drive the 1/2" tap into the smaller bore of the cartridge. It will take  about 15 minutes to slowly work the tap in all the way (maybe 3 turns?). Then  back out the tap... remove needle nose. [remember to turn the tap 1/4 turn back, for each 1/2 turn forward ... this clears the metal particles from the tap and makes the next 1/2 turn forward go smoother].

Next, assemble a 1/2" x 4" threaded rod, so it had threads all the way to the two jam nuts on one end)... If you use a bolt, get one with threads all the way up to the head. you may find it hard to find - so try a carriage bolt and spin a nut all the way up to the head .... continue: 

next on the bolt goes a 1/2 nut (this is the "jacking nut") and a flat washer so the jacking nut can spin easily against the next piece, a 1/2 drive socket (7/8" ) with the square hole toward the washer and jam nuts ( bolt head ).
The open end of the socket faces the brass body of faucet and rests on the round brass lip... having the same inside diameter. This allows a space for the cartridge to be pulled into ( a cavity). Thread the bolt into the tapped cartridge and snug it up so the 7/8" socket is aligned with and resting against the brass body. If the cartridge spins smooth, the threaded rod is GREAT. You can just work with the 1/2" rod and use needle nose (or similar) to stop the  cartridge from spinning, to get the rod threaded into the tapped threads in the cartridge... then, slip on the socket, washer and nuts.

Now snug it up tighter. Check socket alignment. Then begin turning the jacking nut ( the "extra" nut) until it contacts the flat washer and 7/8" socket. Now, as you continue to tighten the jacking nut, it will pull the 1/2 bolt (threaded rod) away from the faucet... and the cartridge will come along too. [You have to prevent the 1/2 rod from spinning while tightening the jacking nut. put a wrench on the bolt head.]
This procedure is bit lengthy and requires some appropriate tools,but this will release the stuck cartridge out.
Thanks. keep updated for any more query.you can rate this solution and show your appreciation.

I replaced a 96909 cartridge with a Moen 1222 cartridge. Now the handle work incorrectly- never pointing to off, when off.

It sounds like the 1222 cartridge is not compatible with your faucet. You may need to replace the cartridge with the correct one for your faucet. If you are unsure of the correct cartridge, you can contact Moen directly for assistance.

Barclay 4073-PL Diverter Bathcock Tub: Thoughts on why the water pressure is low on the hot spigot but not on the cold, and not on any other faucet in the house?

Debris can get into the shower body/cartridge. Pull out the cartridge and flush the shower body and clean out the cartridge. Sometimes you need to replace the cartridge.

I replaced a moen 1222 valve stem becasue i had just a trickle of water. I go the new stem in ok, but still no water. I have the hot water heater diconnected on the water inlet, but the out let is still...

With posi-temp cartridges, if one supply of water, hot or cold, is interrupted, the cartridge automatically restricts the flow of the other water source. This is to prevent you from getting scalded if the pressure on the cold side drops because of a toilet being flushed or any other uses of cold water. The cartridge will only allow cold water to flow through if there is hot water to balance it out. If you restore hot water to the faucet, it will operate properly.

We had our hot water tank replaced and now our water flows really slow out of the tap of our tub. Yet the flow is OK from the shower. We have the single handle faucet. It seems you have to pull the little...

It is not uncommon for one or more faucet devices to go haywire immediately after a water heater change out, especially if the cold water line to the water is galvanized metal pipe and is quite old. while this scenario is the most common, it is not the only possibility. Sometimes it's just plain coincidence in the timing of events.
I would remove and replace the #1222 cartridge, inspect it for obvious debris from the heater replacement, briefly turn the hot water supply on to flush out any possible debris in the valve body itself, then reinstall the cartridge. Valve flushing should always be done before any cartridge gets reinstalled.
If the problem persists, the diverter on the tup spout would be my next focus. Again, debris from the heater replacement could (but far less likely) have affected its function. While not as easy to remove and exactly replace, by taking it off...then turning the water on, you will be able to observe the flow difference..With no difference the problem is in the valve and the cartridge should be replaced....with significant flow difference the, replace the tub spout. Be sure to take the tub spout with you, if it's the problem, when you take it to your plumbing supply store so it can be matched to a replacement. There are many tub spouts for many situations.
Search this site for Moen cartridge removal procedures. I have posted numerous solutions.

I have extremely low pressure from my Moen Posi-Temp 1222 shower valve, but otherwise it functions well. Should I replace the posi-temp cartrige?

Hi Ken--
Positemp cartdiges should deliver years of maintenance free operation. Usually, clogs develope downstream from the cartridge. If the cartridge still works well, that is, if it still pulls and turns freely, and the rest of the house has decent water pressure, check your shower head. Remove the head and test the water pressure. If the water flows better without it, you may have a clogged shower head. Over time, rust and scale can build up inside the shower head and block what would otherwise be decent water pressure. If a visual inspection does not yield any visible blockage, you can consider cleaning the head by soaking it in a calcium removing solution such as CLR. This often helps, but my preference is to replace the shower head completely.
--Hope this helps.

I just bought a repo house which has a grundfos circulation pump u p 15 installed at the water heater. House built 2005 4260 sq. Feet. House has 4 showers only one of them gets hot water. All sinks get hot...

that pump is likely to be a hot water return pump not a booster pump. it sound like a large property so its likely the hot water system requires balancing to get the hot water to the extreme areas. If all the hot outlets have some form of isolation valve try closing all but the affected areas and see if hot water comes out. If so only open the closed outlets enough to give you reasonable flow. This hopefully will force the hot water to the affected areas.

I have been told there is a way to adjust bath tap temperature under the bath is this true? Thanks

is this a standard bath tub?? if so the answer is no only pressure from hot/cold usually thru the access panel other wise you will have to crank up the water heater unless you have an on-demand water heater located near your access panel. which raises a second question. your faucet? is it a single handle for both hot/cold or two individual handles? if its a single handle try opening up your hot water valve in the access panel to allow for more hot water flow and slightly decresing your cold water valve hope this helps good luck!!!!

Can't get cold water

the balancing spool sounds like it is frozen. You need to replace the cartridge. The spool needs to move freely to regulate the water coming through it to keep from scalding a person.
