Typhoid fever is contracted by the ingestion of the bacteria in contaminated food or water, through poor personal hygiene, or close contact with someone who is infected. Patients with acute illness can contaminate the surrounding water supply through stool, which contains a high concentration of the bacteria.
Turn off the main water valve that provides water to the bathtub and open the faucet handle to relieve the pressure. Remove the handle cover cap by prying it off with the blade of a pocket knife. Unscrew and remove the central handle screw, using a Phillips screwdriver. Pull off the handle.
How can I fix a shower faucet valve that is sticky? I have two bathrooms that have been completed in the last year. Both have the same Price Pfister rough-in valve. One is sticky and requires a bit of force to turn on the water (turns on by pulling). It actually has gotten worse over time. The other turns on with a gentle pull of handle. The plumber that installed the sticky one may have pulled out the cartridge and messed it up (rationale: because he messed up other things).
