Ceramic-disc faucets are like cartridge faucets except discs inside the cartridge control the water flow. This type of valve is sturdy and reliable and rarely needs fixing. In fact, many manufacturers offer a lifetime warranty on the cartridge. Leaks can result from faulty rubber seals or a cracked disc inside the cartridge. Since replacement cartridges are expensive, start by replacing the seals arid reassembling the faucet. If it still leaks, replace the cartridge.

Installing Shutoff Valves
Shutoff valves on every water-supply line simplify repairs and allow you to quickly deal with emergency faucet and toilet leaks. For long-term reliability, use ball-type valves and determine whether you need a straight or angled valve.
1. Shut off main water valve. Cut pipe at a point that leaves room to work. Pipe may come up from floor or out of wall. Disconnect old faucet supply lines. Remove burrs from inside and outside of pipe. Install escutcheon plate. Shutoffs are avail able for compression, solder or threaded fittings.
|2. Clean copper pipe with emery cloth or steel brush. For compression fittings, slip compression nut over pipe, lubricate ferrule with Teflon pipe compound and slip ferrule over pipe. For sweat joints, open valve to avoid heat buildup while soldering the joint.
3. Attach supply lines to faucet first. Slide shutoff valve onto pipe. Coat threads with pipe compound. Use two wrenches to tighten compression fittings to hold the valve steady with its handle facing out. Check valve packing nut to make sure it’s tight.
