Danco Cartridge Repair Kit for Delta Single-Handle Faucet Review

What This Review Covers

Buying in cartridges is easier when numbers stay honest. Here we review the Danco Cartridge Repair Kit for Delta Single-Handle Faucet using hub facts for Danco, with emphasis on measurements and constraints you can verify.

Our Summary

The Danco 86970 is for a dripping Delta single-handle faucet with the #70 ball style and needs a repair kit.

The kit is for faucets with a #70 style ball on kitchen and bathroom sinks. The listing says it contains four seats, four springs, two cams, four o-rings, the #70 ball and a hex wrench. It works with hot and cold water, and the listing says it complies with the Reduction of Lead in Drinking Water Act. The plastic construction is described as strong and reliable. The color is brass. The weight is about 0.06 pounds and the pack is about 5 by 3 by 6 inches. The warranty is limited one year. The model is 86970.

Turn off the water at the shutoffs and open the faucet to relieve pressure before you take it apart. Check that your faucet uses a #70 ball before you buy, since Delta uses several styles. Note the order of the parts before removal, and take the old parts to the store if unsure. Close the drain or cover the sink to catch small parts. Use the hex wrench for the set screw and do not overtighten the cap. Flush the faucet after repair to clear debris.

When This Makes Sense

This style of plumbing suits shoppers who already know they need cartridges coverage and want a Danco option with transparent listing details.

It is a weaker match if you need a fully custom install, a different capacity class, or a feature the hub row simply does not list.

Practical Caveats

Trade-offs are normal in cartridges. A design that wins on portability may give up enclosed storage; a long wireless claim may assume open line-of-sight; a high load rating usually assumes even distribution.

Our Storage Pick badge is editorial shorthand for “worth considering in this category,” not a guarantee for every floor plan, campsite, or property layout.

Where It Sits in the Category

Against generic no-name alternatives, Danco listings often win on clearer packaging and easier returns through Amazon — still read the live seller and fulfillment line.

Against premium ecosystems, this unit may look simpler. That can be a feature if you want fewer apps and more straightforward hardware.

Recommendation Frame

Buy the Danco Cartridge Repair Kit for Delta Single-Handle Faucet if the hub numbers and feature set line up with your cartridges job. Skip it if you need a capability the listing does not document.
