What should the pipe diameter at the pump inlet be?
The following changes and additions to pumps and piping may influence acceleration head: Increase pipe diameter to reduce friction loss and liquid velocity. Make sure there is straight pipe for at least 10 to 15 pipe diameters at the pump inlet to minimize turbulence.
How to reduce friction loss in a pump inlet?
Use sweeping elbows rather than 90-degree elbows. Use a larger pump to allow for slower stroke speed. (This can be an expensive solution.) Use suction piping 1.5 to 2 times the size of the pump’s inlet port to reduce friction loss and help ensure an adequate supply of liquid into the pump chamber (s).
What happens when you close an inlet valve on a pump?
As liquid flow is stopped by the closing of one inlet valve, the opposite chamber’s inlet valve is opening. The pressure spike carried by the flow of diverted liquid rushes into the chamber being filled and slams into the diaphragm, stretching and weakening it until premature failure occurs.
What to do if your water pump does not work?
Tip: If a pump fails to work, try your spare before checking the fuses. Preliminary priming occurs when this type of pump is immersed in water but air bubbles sometimes get trapped inside its casing. You’ll hear the motor whirring but no water arrives at the taps.
What to do if your water pump inlet tube is leaking?
If you notice a leak at the water pump inlet tube, it should be replaced. Some may be threaded into the water pump while others may seal with an O-ring and/or hose clamp.
Where is the water pump inlet tube located?
The water pump inlet tube is usually located at the bottom of the water pump and pulls coolant from the radiator into the engine. Over time and due to heat cycling, the water pump inlet tube can corrode and leak.
Where to place eccentric reducer on pump pipe?
Consider using eccentric reducers on the suction side of the pump when a pipe size transition is required. Install the flat side of the reducer on the top when fluid is coming from below the pump. If the fluid comes from the top, the flat portion of the reducer should be mounted on the bottom of the pipe.
What should I do if my sump pump is leaking?
Slowly pour a five (5) gallon bucket of water in the drum to check for proper function. The pump should turn on immediately. If there’s a problem, shut it off and discharge the water. Repair may be necessary. At night, inspect for slow leaks by taking a reading on your water meter. Don’t use any water overnight.
