Notes:
- We recommend installing new rubber parts during any repair. Our re-build guide contains additional information that you may find helpful for repairs on assemblies 2" or under.
- Some manufacturers economize by using a single manual or video to cover a range of related models and sizes. While the assemblies portrayed in your manual or video may not exactly match what you have, general design and repair procedures are the same. We do not produce these manuals or videos and are not responsible for their contents.
- Anybody performing a repair is responsible for following all applicable plumbing and safety rules. Due to the serious dangers of low oxygen in large underground work spaces (such as utility vaults), DO NOT attempt a DIY repair in a vault. Please consult a repair company with the equipment and knowledge necessary to safety enter a vault following OSHA's confined space rules.
- If this all feels intimidating, and you'd like some in-person help with repairs, we do offer step-by-step repair consultations to help guide you through the process. Contact us for additional information.

Click here for video intended to troubleshoot constantly dripping or spraying relief valves.
(Opens in a new window. Instructions in this video focus on the repair of the check valves and will fix most relief valve discharge problems. If you have a slow-opening relief valve (indicated by a relief valve opening point of less than 2.0, as shown on your test report), you should also be cleaning the relief valve parts, especially the diaphragm, and replacing all relief valve rubber components. The general repair video below has additional details on this process, but also includes repair instructions for a wider variety of models, not all of which is specific to the 009 series. We always recommend purchasing new rubber parts for installation during repair. A complete rubber parts kit should be used in the even that a check valve is failing. For a slow-opening relief valve, a relief valve rubber parts kit is less expensive and will usually do the trick.)

Repair manual:
| Watts 775 Series 0.5-2" Repair |
Watts does not produce a video that covers repair of this model. You may wish to consult videos for their 007 series, which has a very similar design. If you are using the 007 series videos as a reference, be sure to have the 775 series repair manual handy, as the design and repair instructions in that document are more closely tailored to the design of your assembly. Where the video instructions differ from the manufacturer's repair manual, always follow the manufacturer's model-specific instructions in the manual.
909 series models
(includes assemblies with models numbers beginning in 909 or LF009)

Click here for general repair and trouble-shooting video.
(Opens in a new window. This video covers a full clean-out. It includes servicing of the first and second check valves, along with the relief valve. It features the lead-free version of this model, the LF909(QT). The 909QT and 909QTHW have the same basic anatomy as their lead-free counterpart, but are made with different materials.)
