- 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.
- Adjust the knob up or down until you've achieved your optimal flow rate, if your pump has a control knob.
- 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
- Cut the flexible hose pipe with a utility knife at the output.
- Slip the hose over a barbed fitting valve with your hands.
- 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
- Cut your PVC pipe with a hacksaw.
- Insert a PVC valve between the pieces of PVC you've cut by slipping it on with your hands.
- Secure in place with PVC glue. Let glue harden for 30 minutes.
Things You Will Need
- PVC glue (if applicable)
- Hacksaw (if applicable)
- Barbed fitting (if applicable)
- Utility knife (if applicable)
- Stainless steel hose clamps (if applicable)
- Philips screwdriver (if applicable)
- In general, a "gate valve" will allow more control over the flow rate than a "ball" valve or "globe" valve.
