Whether you are installing a new water main test pump or repairing a broken one, there are some essential things you need to know. These tips help ensure that your water main test pump is working effectively.
Installing a Hydrostatic Test Pump
A hydrostatic test pump is the fastest way to find leaks in water pipes. It also checks for leaks in new and repaired pipes and old systems.
Generally, hydrostatic test pump testing involves pumping water into a closed pipeline at high pressure. The resultant force is then read on a pressure gauge.
Hydrostatic test pumps are available in various designs, including electric, gas, and pneumatic versions. Choosing the best pump depends on the type of system you will be testing.
Electric pumps are the most common choice. They have a smooth crankcase design that keeps them from rusting. They also have a unique oil bath that keeps the crankcase lubricated. Alternatively, gas-powered pumps are ideal for larger jobs. They offer lower weight and are more durable than electric pumps.
The Reed EHTP500 is a powerful yet compact pump. It weighs 37.5 pounds and provides 500 psi/2.0 GPM. It is ideal for small shops testing fire lines.
Getting an Accurate Reading
Getting an accurate reading from a water main test pump can be a challenge. The best way to accomplish this is to make a pre-test water level measurement. Ideally, this measurement should be done a day before the actual test. This way, you can be sure you have the correct water level for the test.
One way to measure this is by using a barometric sensor. This device allows you to calculate the changes in barometric pressure that occur over a specific period. It can also display the pressure of a given water level as a graph. This can be handy if you test a pump with variable pressures.
In the real world, the cost of obtaining this data is prohibitive. However, a high-tech solution such as a digital tire pressure gauge can be employed if you cannot acquire such a sensor. The resulting performance numbers are of a comparable magnitude to a traditional water pressure gauge.
Troubleshooting a Hydrostatic Test Pump
Performing a hydrostatic test pump test is crucial to several industries. These tests verify the integrity of the pipe network and are often used to detect leaks in chemical plants. It also tests the ability of the pump to maintain a certain pressure level. This is especially important in new construction.
While there are several different kinds of pumps, most are designed to perform a single task. For example, a large transfer pump can quickly move water. This allows it to be used in place of a standard filling system.
When performing a hydrostatic test pump test, you should know that the best way to do it is to perform a complete system check. This includes checking the pump’s water supply, inlet fittings, and output hose. Also, if you use a pump with a pressure regulator, wait until the gauge reaches its maximum pressure before beginning.
Repairing or Replacing a Water Pump
Whether you’re replacing or repairing a water pump, there are some things you need to consider. These include cost, downtime, and availability of parts.
A water pump is a crucial part of the cooling system. It delivers cooling to the engine block. If the pump fails, the engine can overheat. This can cause leaks and damage the head gasket. It also may cause the engine temperature warning light to appear. The pump also helps to distribute coolant from the radiator to the engine.
Faulty pumps can cause strange noises. They may only pump water in a trickle or not at all. This may be a sign of a more severe problem.
If your water pump is malfunctioning, you’ll need to find out what’s causing the issue. A technician can help you with this. They will check your pressure control switch, prime the suction line, and find the root of the problem. They may also recommend a repair or retrofitting.
