How can a doctor tell if you have valve disease?
Those results will help the doctor make a diagnosis. The physical exam may show that you have fluid in your lungs, an enlarged heart, or a heart murmur. A heart murmur is the sound made by blood moving through a narrowed or a leaky valve. Diagnostic tests help determine the location, type and extent of your valve disease.
What are the symptoms of a failing check valve?
Other symptoms of check valve failure include reverse flow and excessive component wear and damage. Check valves will also emit noises as they start to break down. This situation is referred to as “water hammer” and is caused by the disc slamming into the seat of the valve. Water hammer can lead to ruptured pipelines and severe damage.
How are check valves chosen for a valve?
Therefore, check valves must be selected based on the expected flow. This involves choosing a valve with the appropriate valve coefficient (CV) value. The CV value describes the ability of the flow media to open the valve fully; the higher the CV, the greater the flow rates required to open the valve.
How to diagnose and correct reversing valve problems?
Problems experienced with reversing valves fall into four general categories: 1. Valve will not shift from cooling to heating. 2. Valve will not shift from heating to cooling. 3. Valve starts to shift but does not complete reversal action. 4. Valve suffers apparent leak when shifting.

How to check a faulty water inlet valve?
Checking the valve for mechanical failure 1 Disconnect the water supply line from the water valve. 2 Place a bucket under the end of the water supply line. 3 Turn on the water to the supply line and check the flow.

What should I do if my pressure regulator valve fails?
Loosening the screw has the opposite effect. When faced with insufficient pressure, don’t immediately jump to the conclusion that your regulator valve has failed. You may simply need to have your valve adjusted. Virtually all pressure regulator valves have a pre-set pressure limit of 50 psi. Most homeowners consider this too little pressure.
