If the DG-DIS201 does not water as expected, the following checks cover the main installation and operating conditions described in the user manual.
Condition 1: Water leaks around an emitter or connector
Possible Cause
The 1/4" or 5/16" tubing is not fully inserted into the quick connector.
What to Do
- Turn off the water supply.
- Disconnect the affected tubing.
- Check the tubing end.
- Push the tubing fully into the connector.
- Make sure the connection is secure.
- Turn the water back on and check again.
Condition 2: No water comes from an emitter
What to Check
- Make sure the emitter cap is open.
- Check the distribution tubing for blockage.
- Check the emitter for debris.
- Check the main connector filter for dirt or sediment.
Condition 3: Water output is uneven
Possible Causes
- Some emitters are partially closed.
- Tubing or emitters are blocked.
- Too many emitters are operating from one branch.
- Overall system pressure is too low.
What to Do
- Check each emitter.
- Remove debris or blockages.
- Reduce the number of emitters operating on a single branch.
- Use separate branches where possible.
- Confirm that the water supply provides sufficient pressure.
Condition 4: Water pressure is too low at downstream emitters
For larger irrigation layouts, the manual recommends:
- Splitting the main line at the water source using a hose splitter with shut-off valves.
- Watering each branch separately rather than operating every branch at the same time.
This can help improve water distribution when supply pressure is limited.
Condition 5: Tubing comes loose under pressure
Possible Causes
- Tubing is not fully inserted.
- Water pressure is too high.
- Oil or lubricant was used during assembly.
What to Do
- Reinstall the tubing fully.
- Maintain water pressure within 30–60 PSI.
- Do not use oil or lubricants on the tubing or fittings.
Frequently Asked Questions
What water pressure should I use?
The DG-DIS201 operates at: 30–60 PSI
Does the quick connector include a filter?
Yes.
The manual instructs users to make sure the filter is installed inside the 3/4" to 5/16" quick connector before use.
Why is the filter important?
It helps prevent debris and sediment from entering the irrigation system and clogging the emitters.
Can I use glue to secure the tubing?
No.
The manual specifically advises against using glue.
Glue may clog the system and can make future cleaning more difficult.
Can I use oil or lubricant to insert the tubing?
No.
Do not use oil or lubricants during assembly.
They may damage the tubing or fittings and increase the risk of connections coming loose under water pressure.
How many emitters can I connect?
The manual provides guidance for a system using all 16 emitters.
For that configuration, it recommends no more than:
8 emitters per four-way connector / 2 emitters per branch
to help maintain adequate water pressure.
Can I use a hose splitter?
Yes.
The manual recommends using a hose splitter where appropriate to improve water distribution efficiency.
Why should I water separate branches independently?
If the available water pressure is low, running fewer branches at one time can improve flow to the active emitters.
How do I remove tubing from a quick connector?
Press the connector's inner release ring firmly, then pull the tubing outward.
Should I flush the tubing before installing the emitters?
Yes.
The installation illustrations recommend flushing the tubing with clean water for approximately 2 minutes before final emitter installation.
Maintenance
Clean the Filter
Check the filter inside the water-source connector periodically.
Remove debris or sediment when necessary.
Inspect the Emitters
If an emitter produces weak or uneven flow:
- Check that it is open.
- Inspect it for blockage.
- Clean visible debris as needed.
Keep Tubing Free from Kinks
Kinks in the tubing may:
- Restrict water flow
- Cause uneven watering
- Trap water during drainage
Straighten kinked sections when necessary.
Winter & Long-Term Storage
Before freezing temperatures or hard frost:
- Turn off the water supply.
- Completely drain the irrigation system.
- Check all tubing sections for trapped water.
- Pay particular attention to kinks in the 1/4" tubing, as they may prevent complete drainage.
- Store components appropriately after drainage.
Water remaining inside fittings or tubing may freeze and damage water-holding components.
Safety & Use Notes
- Do not operate above the recommended 60 PSI.
- Do not use oil or lubricants during assembly.
- Do not use glue.
- Keep the filter installed.
- Make sure tubing and end plugs are fully inserted before pressurizing the system.
- Drain the system before freezing conditions.
