you have trash in your line take the shower head off and remove trash or possibly in water valve at shower
Some causes for a sudden water pressure drop: 1) A big leak on the main supply line. 2) one or more faucets or shower heads opened on the same water line. 3) A utility water pump failure.
The water pressure in my house is about 140PSI. Which is definitely dangerous. It happens more often than you would think. What happens is a city will use water supply lines which are too small for the water requirements. Therefore, they have to increase the pressure. You wouldn't want a pressure relief valve, because then if the pressure was too high, it would just spray water everywhere to release the pressure. You would want a pressure regulator installed, which is what I am working on for my house right now. Just to let you know though, you may have to get a thermal expansion tank for your water heater if you don't have one. See, the new pressure regulators have a check valve in them, which prevents water from traveling back into the city pipes once it has gotten into your house. When your water heater heats the water, the air bubbles in it expand, which increases the water pressure, and will probably cause your pressure relief valve on your water heater to blow. You can get a cheap water pressure meter at any improvement store to check it out. 50-60 PSI is ok. I would say you could take it up to 70 or 80 PSI safely.
Only if if has a leak.
It is the drain for the Temperature and Pressure relief valve (T&P valve, or TPV). It's function is to release pressure from the water heater if the pressure or temperature of the water exceeds preset limits. Do not cap off the pipe, or remove the T&P valve or alter it in any way. Doing so could cause serious injury or death! If you notice water dripping or running from the pipe, call a plumber to check it.
the velocity of the metals and the engine is going to be in his bad behavior.
If you have a new pressurised water system there is a possibility that the added water pressure could cause a leak.
A malfunctioning water heater can cause hot and cold water to surge through the shower heat. A faulty water pump can also cause this problem.
There are a couple of reasons why a 1999 Oldsmobile Alero ac heater to stop working. The heater coil may need to be replaced or the HVAC blower motor may need to be replaced.
It will not cause low water pressure. It will cause a loss of heated water because the heater will not be able to recover fast enough. It has nothing to do with pressure.
There could be several reasons why the hot water in your shower only lasts for about four minutes. It could be due to a small water heater capacity, a malfunctioning heating element in the water heater, or issues with the shower fixture itself. It's best to have a professional plumber inspect the system to identify and address the specific cause.
Only if installed incorrectly
A squealing heater is more than likely a fan belt. It may be loose, or it may be worn and need replaced.
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)
Your heater core behind the glove box has gone bad and needs to be replaced.
now when you say replaced heater fan multi speed are talking the fan or the switch because ther is a fan speed resitor that can go bad and fan only works on high speed which can cause conector to get very hot and cause insolation on the wires to melt and cause a short in the harness making fan run constantly.
A bad heater core / it needs to be replaced
Heater Core for sure. Get this replaced and you will have no more problems.
