A Calimesa shower that drips, will not hold temperature or has a handle that sticks usually needs a new cartridge or seals, and a plumber can often do that without opening the wall. A cracked or discontinued valve body is replaced. Call the number on this page to be connected with a local plumber in Calimesa.

About Calimesa
Calimesa is a foothill city on I-10 between Yucaipa and Beaumont. It grew from a small rural town of single-family homes and ranches, and large planned developments such as Summerwind Ranch at Oak Valley are adding newer subdivisions. That means two very different sets of bathrooms: older homes whose valves may be decades old, and new homes with current pressure-balancing valves. Water service is split between South Mesa Water Company and Yucaipa Valley Water District, and which one serves you depends on the address. Each provider's annual water quality report lists the hardness for its customers, and water in this region generally leaves scale, which wears cartridges over time.
What to do now
- Shower running and won't stop? Close the main shutoff for the house. On larger rural lots, it may be near the meter at the road.
- Just dripping? Schedule a repair, and note whether the drip is from the head or the spout.
- Temperature jumping? Test the water by hand before stepping in, especially for children or older adults.
- Find the brand on the handle or trim and take a photo.
- Check for water damage on the other side of the wall.
Signs and likely causes
| Symptom | Likely cause |
|---|---|
| Drip after shutoff | Worn seals, seats or cartridge |
| Temperature spikes | Pressure-balance spool sticking |
| Stiff handle | Mineral scale on the cartridge |
| Weak shower flow only | Clogged inlet screens |
| Spout and head both running | Worn diverter |
| Wet drywall | Leak at the valve body or a joint |
Cost factors
- Cartridge or rebuild versus a new valve body
- Parts for the brand in your home, which in older ranch houses can be hard to find
- Access through tile or from a closet behind the shower
- Any supply pipe repairs found at the valve
- Permits. The City of Calimesa Community Development Building & Safety Division, at 908 Park Avenue (909-795-9801 ext. 226), handles plumbing permits; ask whether your job needs one.
If the problem turns out to be on the water provider's side, check your bill to see whether South Mesa Water Company or Yucaipa Valley Water District serves you, and call them.
