How do I find the model number on my 702207310?
The model number for your Sears single handle combination tub and shower faucet is typically printed on the original packaging and paperwork; on the faucet itself, it is most often found on the valve body behind the handle and trim. Use the exact model number to match repair parts.
Shut off the water supply first, then check these common locations:
- Behind the handle: remove the handle and look on the valve body casting
- Behind the escutcheon (trim plate): the back side of the plate or the wall-side of the valve
- On a tag or sticker: sometimes attached to the supply lines or valve body
- On the tub spout or diverter area (less common)
- On your purchase receipt, installation invoice, or saved product paperwork
- Turn off water at the stops or main shutoff.
- Remove the handle set screw and pull the handle.
- Slide off the trim sleeve; loosen and remove the escutcheon if needed.
- Wipe the valve body clean and look for stamped or molded numbers.
For this Sears faucet, the model number format is:
| Item | Example | Why it matters |
|---|---|---|
| Model number | 702207310 | Ensures correct cartridge, seats/springs, and trim compatibility |
| Brand | Sears | Helps narrow diagrams and repair kits |
Tub and shower faucets often have multiple cartridge and trim variations that look similar. Using the exact model number prevents ordering the wrong cartridge, O-rings, or handle hardware.

How do I troubleshoot my 702207310?
To troubleshoot your Sears 702207310 single handle combination tub and shower faucet, start by identifying the symptom (drip, low flow, temperature issues, or diverter problems) and then isolate whether the cause is the cartridge, mineral buildup, or a supply issue. Most fixes involve cleaning or replacing wear parts.
- Drips from tub spout/showerhead when off: cartridge or seats/seals worn
- Low flow: clogged showerhead/aerator, debris in cartridge, partially closed stops
- Temperature swings: failing cartridge, pressure imbalance, hot-side restriction
- Water comes from tub spout during shower: diverter worn or spout diverter failing
- Leak at handle/trim: O-ring or cartridge seal, loose retaining nut
- Confirm both hot and cold shutoff valves are fully open.
- Check the showerhead for scale; clean or temporarily remove to test flow.
- If symptoms persist, shut off water and remove the handle and trim.
- Inspect for a loose retaining nut/clip and signs of corrosion or mineral buildup.
- Pull the cartridge; look for torn seals, scoring, or debris.
| What you see | Most likely cause | Typical next step |
|---|---|---|
| Drip that worsens over time | Cartridge wear | Replace cartridge and seals |
| Flow improves with showerhead removed | Clogged showerhead | Descale or replace showerhead |
| Leak only when turning handle | Handle seal/O-ring | Replace O-ring, verify tightness |
Troubleshooting by symptom prevents unnecessary wall or valve-body work. In many cases, restoring proper sealing and clearing debris returns normal pressure and temperature control.

What is the average lifespan of 702207310?
A single handle combination tub and shower faucet like Sears model 702207310 typically lasts 15 to 20 years. In most homes, the cartridge and seals wear out sooner and are the parts most commonly replaced to extend the faucet’s life.
These components determine real-world lifespan more than the valve body:
- Cartridge (causes dripping, temperature swings, low flow)
- O-rings and seals (causes leaks behind the wall or at the handle)
- Diverter (causes water to leak from the tub spout when showering)
- Handle hardware (stripped set screw, loose handle)
- Mineral buildup in passages (reduces flow and affects mixing)
| Factor | Effect on lifespan | What you can do |
|---|---|---|
| Hard water/mineral scale | Shortens cartridge and seal life | Periodic cleaning, consider water treatment |
| High water pressure | Increases wear and leak risk | Keep pressure in a typical 40 to 80 PSI range |
| Frequent use | More cycles, faster wear | Replace cartridge at first signs of drift/drip |
- Drips from the tub spout or showerhead when off
- Handle gets stiff or gritty
- Temperature is hard to control or suddenly changes
- Water leaks at the handle or behind the trim
Most “faucet failures” are serviceable wear parts, not a bad valve body. Replacing the cartridge and seals early prevents water damage and keeps the shower temperature stable.
