Wilkins repair resources
(Select your model below. Resources within each section are grouped by assembly size.)
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.

Note: Wilkins does not offer a video specific to the 720A. There are third-party repair videos available on YouTube. Because these are not produced by the manufacturer, or one of our trusted suppliers, we cannot endorse the repair procedures they use. If you are referring to these third-party videos as a reference, please take care to follow the exact repair instructions provided in the above manual, and be exceedingly careful as you remove parts, to avoid damaging them.
model 950XLT
Note: Wilkins does not offer a video specific to the 950XLT. The video below covers repair of this assembly's sister model, the 950XL, which is nearly identical except for the orientation of the two check valves on the assembly body. Where the video instructions differ from the manufacturer's repair manual, always follow the manufacturer's model-specific instructions in the manual.
