Delta shower controls are one of the most popular fixtures on the market, and have proven very reliable with an excellent warranty, however nothing lasts forever and your Delta Monitor shower control may require the occasional replacement part.
Nearly all plumbing problems with showers are caused by the cartridge and rubber parts inside shower control, but these are easily replaced with only simple tools that most homeowners should have. So if your shower is leaking, squealing, thumping or not producing a solid flow of water, have a look at the control's cartridge.
Removing A Delta Monitor Cartridge
- The water to your shower, both hot and cold must be shut off and checked, before attempting any repairs. There may be isolation valves inside an access panel behind the shower wall(usually in a closet).
- Remove the shower control's handle using a screwdriver or allen key(depends on model) to expose the cartridge assembly.
- Remove the trim sleeve by pulling and twisting.
- Using a pair of large jawed pliers, remove the brass retaining nut that holds in the cartridge.
- The cartridge can now be pulled out and inspected for any visible defects.
- Inside the valve body there will be little black rubber seats and springs that are often to blame for poor operation. Remove them with a pair of needle nose pliers. These rubber seats and springs are found in many delta products and can be purchased in most plumbing supply stores.
- Check all rubber parts (o-rings, seats, gasket) for damage before attempting to replace the cartridge.
- If replacement parts are required contact the warranty department or a delta distributor for parts.
