i would advise that you get some Teflon tape at the hardware store this will help seal the screws so water doesn't leak out when you turn it on. 1. first you need to unscrew the shower head off.2. then wrap the screw threads in the Teflon tape(this part can be a little tricky and if you know anything about telfon you can quess why).3. then just srcew they new shower head on but make sure you do it nice and tight.
that's for your standard shower head but if you have one of those hose shower heads there some extra steps and a lot more teflon. 1. do steps 1-2.2. then but on the base that holds the shower head. 3. then wrap teflon on the part of the hose that goes in the base.4. put hose in base.5. attach hose to head then put head in base holder.
That how you but on a new shower head.
changing a shower valve can be sometimes impossible with out cutting a hole in the wall behind it. If you have a shower valve that is leaking through the valve and out of the shower head when shut off then I recommend trying to find new cartridges or replacement seals for the valve. If you need to replace the shower valve then I would cut a hole in the sheet rock behind the shower valve big enough so you have enough room to replace it. Sometimes if you can't get behind the shower wall and your water pipe isn't galvanized then it might be possible to change the valve through inside the shower but it can be a real struggle and most of the time you will need a wider trim plate. If you don't have much experience in soldering or using pex pipe and fittings then I would save you a headache and call a service plumber.
You shut off the water supply, then take the shower control or spout apart (depends where the diverter is). Remove the diverter and take to Plumbing store or HD to get a new one. You may have to get a new spout if it contains a sealed diverter. Replace it in reverse order.
Either tear out the wall around the valve or most showers and tubs will have a closet behind them where you can cut an access panel to get to the valve from the back side. You then either repair the wall or they make a panel to cover the hole for future access.
That would depend if the drain is screwed / No Hub / plastic or caulked ( lead and Oakum)
With a handle or lever and some like Delta have a option to use a ball type
This depends on what shower fixture you mean, shower head? mixer? tap? shower floor drain?
Cut out the drywall in the wall behind the shower. Replace the valve. Patch the drywall.
Though not a plumber, I can say that shower valves are usually made of brass(a very good material). Therefore they are also expensive to replace (50 dollars for the valve, 150 dollars per shower valve if done by a competent plumber). Therefore, when you notice a leak coming from your shower, try to replace the seat washer (usually the hot water side needs to be replaced first). If you still have a leak, it's time to replace the shower valve.
Replace the shower valve.
You replace it. If it's a squeal, you replace the shower head fist. If that doesn't make the noise go away, you replace the shower control valve. Odds are since you came online to ask how to fix it, you're not qualified to replace the control valve. Call a plumber now or call a plumber and a drywall contractor to fix it after you make your "repairs"
You have to replace the cartridge
If you mean shower valve, screws are for shower valve coverplate.

Aerator in shower head is plugged up. Unscrew head, clean it out, and replace. Make sure you have teflon tape on hand for the treads on the shower arm when putting the head back on.
This will involve breaking open the shower wall, taking out the one handle unit and rearranging the pipework in order to replace it with a two handle valve unit. This not a DIY job, call a plumber to do this to save yourself the headache of having to call one later
A trim kit is just the outside parts that you see. This will make you faucet look better, but it wont affect the function of your old valve. If your shower valve doesn't work right, replace it.
Your water pressure is low. Consequently, when cold water is diverted to another application such as a toilet or a sink, the amount of cold water available at the shower mixing valve decreases as the low pressure is unable to keep up with the shower's demand. This causes a hotter mixture at the shower head. The solution is to either improve the cold water supply to the shower or to replace the shower control valve with a temperature compensating type. Pressure balancing is the cheapest and simply changes the shower temperature according to the pressure in the cold and hot water lines. When the toilet or sink is used, reduced pressure to the shower valve is detected and the valve reduces the hot water pressure, thereby maintaining the temperature. The more sophisticated approach is a thermostatic shower control valve. These are significantly more expensive, but will not reduce the pressure at the shower head (a drawback of the pressure balancing valve). The thermostatic valve would be required when one shower control valve is operating several shower heads. Moen, Kohler and Delta all make both types of control valves. They can be readily obtained from a local plumbing supply house.
