You should not really have over 80 pounds of pressure. But a lot of people do.
NO -- even with high pressure it should work ok
Shower body or pan not properly supported or the joint not properly caulked possibly a fiberglass pan with plastic piping
you have trash in your line take the shower head off and remove trash or possibly in water valve at shower
A dirty or clogged screen can cause the low water presser remove shower head and clean. If not it could be calcium deposits built up on shower head if so soak shower head in a cleaning solution for several hours if that dose not work buy a new shower head. (note some shower heads have a low flow re-stricter in some cases you can remove this and get more water pressure)
If oil pressure is low it certainly can cause the car to overheat. This is because the mechanisms are not being properly lubricated with enough oil.
If you have a new pressurised water system there is a possibility that the added water pressure could cause a leak.
My first thought is a leaky hot water line.
Do you have your own well? If so the pressure switch has kicked in and the pump is running. If the pressure tank is in good shape, there is usually enough residual pressure in the piping system to be suitable, but when it drops the pump kicks in and that can take a bit. Did someone flush a toilet? A toilet refilling will take water out of the system, thereby reducing the system pressure. When it's finished filling, the pressure returns to normal.
The spring on the bottom of a radiator cap will cause it to fail. If the spring does not work properly it can lead to pressure escaping from the radiator which can overheat the vehicle.
if its just a shower and no tub spout then it most likely must be in your shower head and if its a hand held shower head (with a flexible hose attached) it most likely has a bad seal or some other way which allows air to get inside and drain the water out slowly. The same can be for a shower with a tub spout diverter and the shower head has a bad seal thus letting the water drain down the tub spout and it can be a real slow leak to cause the squeaking noise 20 minutes later, my guess of the squeaking noise would come from the air being pushed inside the shower head.
== Answer== I don't think so, but get the air out of lines to make sure.
Either the fuel pump isn't working properly or the fuel filter is plugged.
YOU DON'T the ASME /NBBI codes have certain requirements regarding boiler manufacturing and a high pressure boiler can cause severe damage if it is not properly designed and routine maintenance performed ....
