What is the Makita Toilet Repair Kit?
The Makita Toilet Repair Kit is a set of specialized bits and sockets designed to be used with a 1/4" hex impact driver or drill. It includes a toilet bolt socket, a flush valve socket, a fill valve socket, and a universal joint. The kit is built to speed up the process of removing and installing toilet bolts and nuts, which are often in awkward, hard-to-reach locations behind the toilet base.
Who is it for?
This kit is primarily aimed at professional plumbers and maintenance technicians who replace multiple toilets per week. It is also suitable for serious DIY enthusiasts who own a Makita impact driver and want to avoid the frustration of using a standard wrench in a cramped bathroom. It is not for a homeowner who only plans to replace a toilet once every ten years, as the cost may not justify the convenience.
Performance and Build Quality
The bits are made from chrome vanadium steel, which provides good durability against rust and wear. The deep sockets are designed to reach nuts that are recessed into the toilet base. User reviews on Amazon and home improvement forums indicate that the kit works well for standard toilet bolts, but some users report that the bits can be too short for certain toilet models with very deep bolt recesses. The universal joint adds flexibility, but it can also reduce torque transfer from the impact driver.
What to Check Before Buying
Before purchasing the Makita Toilet Repair Kit, verify that your impact driver has a 1/4" hex collet. Check the depth of your toilet's bolt recess by measuring the distance from the base of the toilet to the nut. Standard toilets are compatible, but some modern "chair height" or "comfort height" models may require longer bits. Also, consider if you already own a standard socket set that might include the same sizes.
Mistakes to Avoid
A common mistake is using the impact driver on the highest torque setting, which can easily snap the plastic bolts found on many toilets. Start on a low setting and increase only if needed. Another error is using the universal joint for every bolt; use it only when the bolt is at an angle, as it can make the tool wobble. Finally, do not use the kit on corroded or rusted bolts without first applying penetrating oil, as the impact force can strip the bolt head.
Alternatives to the Makita Toilet Repair Kit
If you are not invested in the Makita ecosystem, consider a universal toilet wrench from brands like Ridgid or a simple multi-tool with a right-angle attachment. For most DIYers, a standard 9/16" combination wrench and a flathead screwdriver will do the job, though it will take longer. Milwaukee also offers a similar toilet repair bit set that may be a better fit for Milwaukee tool owners.
FAQs
Does the Makita Toilet Repair Kit work with all toilets?
It works with most standard two-piece and one-piece toilets, but it may not fit toilets with very deep or custom bolt recesses. Check the bolt depth before buying.
Can I use this kit with a drill instead of an impact driver?
Yes, the bits have a 1/4" hex shank that fits into standard drill chucks. However, a drill lacks the high torque of an impact driver, so removal may be slower.
What sizes are included in the kit?
The kit typically includes a 9/16" toilet bolt socket, a 1/2" flush valve socket, a 7/16" fill valve socket, and a universal joint. The exact contents are listed on the package.
Is the Makita Toilet Repair Kit worth the money?
For a professional plumber, yes, because it saves significant time. For a homeowner doing one job, a manual wrench is more cost-effective.
Will the kit strip plastic toilet bolts?
It can if used on the highest torque setting. Always start with a low torque setting and use a gentle trigger pull to avoid stripping.
Does the kit include a case for storage?
Most versions come in a small plastic or fabric case that keeps the bits organized. Check the product listing to confirm.
Can I use this kit for other plumbing tasks?
Yes, the sockets can be used on other nuts and bolts of the same sizes, such as those on faucets or shower drains. It is not limited to toilets.
Is the kit compatible with Makita's 18V or 40V impact drivers?
Yes, it works with any impact driver that has a 1/4" hex collet, including all Makita 18V LXT and 40V XGT models.
How long do the bits last?
With regular use on standard bolts, the bits can last for years. They will wear faster if used on rusted or hard steel bolts without lubrication.
What is the warranty on the Makita Toilet Repair Kit?
Makita offers a 1-year limited warranty against defects in materials and workmanship for this accessory kit.
Can I buy replacement bits separately?
Replacement bits are not commonly sold individually. You may need to buy a new kit if a bit is lost or broken.
Does the kit work on commercial toilets?
It can work on some commercial toilets, but many have larger bolts or different thread sizes. Check the bolt specifications before use.
Our verdict
The Makita Toilet Repair Kit is a well-made, time-saving accessory for professionals who already own Makita tools. For the best overall performance, we recommend the Makita B-65370 kit. For budget-conscious DIYers, a standard wrench set is a more practical choice.
