Rothenberger Tap Repair Kit Review

The Rothenberger 70155 is the standard kit for DIY tap refurbishment. It centers on a steel reseating tool with a plastic handle that allows you to grind down the valve seat to create a smooth sealing surface. Owner reviews on retailer sites note that the grinding paste is effective for removing limescale and minor pitting, and the included seals fit most modern ceramic disc taps and traditional washer taps.

However, some users report that the plastic handle can flex under heavy pressure, making it less suitable for daily professional use. The seal selection covers common sizes but may not include less common metric or proprietary seals found in some European or Asian taps. Overall, it is a reliable kit for occasional home use and light maintenance.

The Rothenberger 70156 is the professional-grade version of the standard kit. It features a fully metal reseating tool with a T-handle, offering better leverage and durability for repeated use. Owner reviews highlight the improved grip and the ability to apply more consistent pressure when grinding valve seats. The expanded seal set includes additional sizes for mixer taps and less common configurations.

While the price is higher, the build quality justifies the cost for plumbers or serious DIYers who tackle multiple tap repairs each year. The heavier weight and larger case mean it is less convenient for quick carry-around jobs, but the performance and longevity are superior. Some users note that the included paste is the same as the standard kit, which is fine for most tasks.

The Rothenberger 70157 is the bare-bones reseating tool, identical to the one found in the 70155 kit but sold alone. It is ideal if you already have grinding paste and a selection of seals, or if you only need to reseat a single tap. Owner reviews note that the tool works well for smoothing out minor seat damage, but the lack of included consumables means you need to buy them separately.

This option is best for users who want to save money or have specific seal preferences. However, the plastic handle is the same as the standard kit, so it is not built for heavy daily use. For occasional jobs, it gets the job done at a lower cost.

The Rothenberger 70158 is tailored specifically for ceramic disc taps, which are common in modern homes. It includes a reseating tool, ceramic disc seals, and O-rings, along with grinding paste. Owner reviews indicate that the seals fit popular brands like Hansgrohe and Grohe, but compatibility with lesser-known brands may vary. The reseating tool is the same as the standard kit, with a plastic handle.

This kit is a good choice if you know you have ceramic disc taps and want a targeted solution. The specialized seals reduce the guesswork compared to a general kit. However, it is not versatile for other tap types, so it is best for users with only disc taps in their home.

The Rothenberger 70159 focuses on mixer taps, which have different seal configurations than standard pillar taps. It contains a reseating tool, mixer-specific seals, and O-rings. Owner feedback suggests the seals fit common mixer brands like Grohe and Ideal Standard, but some users report needing to purchase additional seals for less common models. The reseating tool is the same plastic-handled version as in the standard kit.

This kit is useful for homes with multiple mixer taps, as it provides the right seals for those units. The main limitation is its lack of versatility for other tap types. If you only have mixer taps, this kit simplifies the repair process, but for a mixed household, a general kit may be more practical.
