If you have a union in the suction piping as many well systems do it may be the culprit. some times tightening the union will fix the problem.
Another place air can enter is through the pump seal,if it is worn it may allow air to be pulled into the pump when it is running. replacing the seal can sometimes fix the problem. If you are losing the prime on your well system the problem is between the check valve and the well,if not the problem is between the check valve and the pump.
check your PCV Valve
Need to check if blow-by valve is working correctly.
WP on a check valve typically stands for "Working Pressure," indicating the maximum pressure at which the valve can operate safely. This specification is crucial for ensuring the valve's reliability and performance in a fluid system. It's important to select a check valve with a WP rating that meets or exceeds the system's operating pressure to prevent failures.
Check the valve timing and the ignition timing. If both are good then check the compression in all the cylinders.
Thermostat possibly stuck open or heater control valve broken. Now if you mean the blower motor has stopped working, check the fuse, blower motor itself, or the blower motor resistor pack.
Check the specs for the vehicle you are working on (You can find them on the net if you do not have the manual) and the torque requirements will be there. Do not over torque the bolts as removing a broken valve cover bolt is a pain. Good luck.
You did not say what you are working on. but you can check the plugs, wires, coil, and maybe the fuel injector low engine compresson, broken valve spring.vaccum leak... dist cap. Realey need more info.
If your hot water faucet is not working properly, you should first check if the hot water supply valve is open. If it is open and the issue persists, you may need to check for any blockages in the faucet or the hot water pipe. If you are unable to fix the problem yourself, it is recommended to contact a professional plumber for assistance.
intex sand filter is not working on filter only working on recirculate position.....what should we do
check the idle control valve not that hard to replace and inexpensive
Check the temperature control valve. You're probably allowing hot engine coolant through the rear heater coil.
replace only when u get a check engine light. the valve is good for the life of the motor(should be)
