How often should you replace the shower valve?
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.

What is the purpose of a thermostatic mixing valve?

How do you repair a noisy shower?
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"

How do you fix the clicking noise coming from the valve behind your shower wall after taking a shower if you were told it might be a valve adjusting for pressure?
If the noise is only for a few moments after taking a shower, its the expansion on the hot water side. Water lines going through studs will expand and make noise. the only way to fix this is to get in the wall and either loosen the pipe or tighten it with a shim.
Where is the mixing valve in the boiler?

There is no specific temperature, on the shower unit there is a 'mixing valve' which allows you to adjust the temperature to individual requirements, up to the maximum that the heater is set or the lowest value where only unheated water is delivered.
Installed new shower mixing valve there is a drip on one of the threaded 90 can't tighten without cutting the valve free is there anything to seal drip at fitting?
No. A little confused by the description of a threaded 90 and having to cut the valve free. Every shower I have ever done the final connection to the valve goes on with a nut. You should be able to take one side loose and leave the valve in place. Disassemble to the leak and replace.
How do you keep shower temperature from changing when someone flushes the toilet or uses another sink?
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.
