Danco Cartridge Repair Kit for Delta Single-Handle Faucet, Brass (86970)

Best for: Single-handle Delta bathroom faucets that drip or feel stiff at the lever.

This kit suits homeowners with a single-lever Delta faucet who want a cartridge-focused fix rather than replacing the whole fixture. Because the cartridge controls both water flow and temperature, replacing it is often the step that stops a drip from the spout.

Key specs

• Designed for Delta single-handle faucets
• Brass-bodied cartridge kit
• Part number 86970 listed in the product name

Pros

• Targets the most common failure point in single-handle Delta faucets
• Brass construction is a durable option for the cartridge body
• Clear model-specific naming helps confirm compatibility

Cons

• Only suits single-handle models, so two-handle faucets need a different kit
• Installation still requires shutting off supply valves and some basic tools

Bottom line: The best starting point for owners of a single-lever Delta bathroom faucet who want a focused cartridge replacement.

Buying Guide

Handle Style: Single Lever or Two Handles

Look at your faucet before you order. A single-lever Delta uses a cartridge, while a two-handle model typically uses stems, seats and springs. Ordering the wrong type is the most common reason a kit goes back.

Good picks for this: Danco Cartridge Repair Kit for Delta Single-Handle Faucet, RP25513 Faucet Stem Replacement for Delta 2 Handle Faucet Cartridge

Part Numbers and Model Compatibility

Find the model or part number stamped on the faucet body or in the original manual. Match it against the part numbers in the kit listing, such as RP24096 or RP25513, before buying.

Good picks for this: RP25513 Faucet Stem Replacement 4 Pack, 2-Pack for RP25513 Faucet Stem Assembly

Included Parts: Seats, Springs and Stops

A stem alone may not fix a leak. Seats, springs and 1/4 turn stops wear over time and are often worn with the stem. Kits that list these parts give a more complete repair.

Quantity and Spares

Multi-packs make sense for landlords, multi-bath homes or anyone who wants a spare set. A single kit is enough for one faucet with one repair.

Material and Durability

Brass bodies tend to hold up better than plastic under daily use and temperature changes. Rubber seals and springs should be checked for the same material standards your faucet originally used.

Ease of Installation

Plan on turning off the supply valves, removing the handle, and using a basic set of tools. Keep a towel, a small container for screws, and a photo of the original parts layout nearby.

When to Replace the Whole Faucet

If the body is corroded, the spout is cracked, or the parts are no longer available, a repair kit may not be worth it. Reviewing the signs in a dedicated guide like Bathroom Faucet Repair Kits: How to Fix a Leaky Faucet in 6 Steps can help you decide.

FAQ

What is a delta bathroom faucet repair kit?

A delta bathroom faucet repair kit is a set of replacement internal parts, usually a cartridge or stem assembly with seats, springs and stops, designed to fix dripping or stiff Delta faucets without replacing the whole fixture.

How do I know which delta bathroom faucet repair kits fit my faucet?

Check whether your faucet is single-handle or two-handle, then find the model or part number on the body or manual. Compare that number with the part references listed in the kit, such as RP25513 or RP24096.

Do I need to replace seats and springs with the stem?

Often yes. Seats and springs wear alongside the stem, and replacing them together reduces the chance of a leak returning soon after the repair.

Are delta bathroom faucet repair kits hard to install?

Most owners with basic tools can complete the job. Shut off the water supply, remove the handle, swap the internal parts, and reassemble. If you are unsure about the valve or water supply, consult a licensed plumber.

Why is my Delta faucet still dripping after a repair?

Common causes include a partially seated cartridge, debris in the valve, or a worn seat that was not replaced. Recheck the installation and the supply shutoff. If the problem continues, a plumber can inspect the valve.

Should I buy a multi-pack kit?

A multi-pack is useful for multi-bath homes, rentals or keeping a spare. A single set is enough for one faucet with one repair.

How often do faucet cartridges need replacing?

There is no fixed schedule. Cartridges wear with water quality and usage, so replace them when you notice dripping, stiffness or temperature control problems.

Conclusion

For a single-lever Delta faucet, the Danco kit is the most direct fit. For two-handle faucets, the RP25513 four-pack suits households that want spares, the two-pack suits a repair plus a backup, and the budget two-pack suits a straightforward single repair. Confirm your model before ordering, and match the kit to your handle style.
