How to Adjust Flow on Pond Pumps

• 1

  Check your pond pump to see if it includes a flow-adjustment valve or control knob. This will normally be clearly labeled. It will be located on the pump itself.

• 2

  Adjust the knob up or down until you've achieved your optimal flow rate, if your pump has a control knob.

• 3

  Installing a flow-reducing valve on the output of your pump if your pump does'nt have a control knob is worthy of consideration. To do this, you'll need to cut the outlet pipe and splice in a valve. The exact specifications will depend on what kind of pipe you have.

Adding a Flexible Hose Outlet Pipe

• 4

  Cut the flexible hose pipe with a utility knife at the output.

• 5

  Slip the hose over a barbed fitting valve with your hands.

• 6

  Secure the hose in place with stainless steel hose clamps, by tightening the clamps over the hose with a Philips screwdriver.

Splicing In a PVC Pipe Valve

• 7

  Cut your PVC pipe with a hacksaw.

• 8

  Insert a PVC valve between the pieces of PVC you've cut by slipping it on with your hands.

• 9

  Secure in place with PVC glue. Let glue harden for 30 minutes.
