FAQs

There are various disinfectants along with natural occurring contaminants and hard minerals that are damaging to your plumbing system and more importantly are unhealthy for you and your family. San Diego’s 2021 annual drinking water quality report gives you the breakdown of everything found in the water that comes out of every San Diego resident’s sinks and fixtures.

San Diego water tested on average 0.30ppm with a high of 0.49ppm. Chlorine is extremely irritating to the skin and can cause severe burns in humans. Chlorine is a potent irritant in humans to the eyes, the upper respiratory tract, and the lungs. Several acute (short-term) studies have reported the following effects: tickling of the nose at 0.014 to 0.054 parts per million (ppm); tickling of the throat at 0.04 to 0.097 ppm; itching of the nose and cough, stinging, or dryness of the nose and throat at 0.06 to 0.3 ppm; burning of the conjunctiva and pain after 15 minutes at 0.35 to 0.72 ppm; and discomfort ranging from ocular and respiratory irritation to coughing, shortness of breath, and headaches above 1.0 ppm. Higher levels of chlorine have resulted in the following effects in humans: mild mucous membrane irritation at 1 to 3 ppm; chest pain, vomiting, dypsnea, and cough at 30 ppm; and toxic pneumonitis and pulmonary edema at 46 to 60 ppm.

As drinking water travels from the city’s water treatment plant through the distribution system to homes and businesses, a disinfectant residual must be maintained in order to prevent growth of potentially harmful microbes. In San Diego, chloramines are used for this purpose. The City performs frequent and comprehensive monitoring to ensure that disinfectant levels remain in the proper range throughout our large and complex distribution system. The Maximum Residual Disinfectant Level (MRDL) is 4.0 ppm. In 2021 the City analyzed 7572 samples for chloramines throughout the distribution system; the average residual was 2.0 ppm and the maximum was 3.8 ppm.

To maintain proper water flow throughout the carbon media a backwashing head is critical. These systems are not susceptible to pressure loss over time or channeling. Also, they are not as susceptible to empty bed contact time leakage, suspended-solid fouling and biological growth. These systems are versatile and can be customizable for different kinds of water quality problems. Backwashing can also reduce mud-ball formation, as in upflow systems. These systems also require less preparation time for the contractor and installer by reducing air-pocket problems.

That all depends what you are trying to remove from your water. A backwashing carbon filtration filters out harmful contaminates, impurities that make your water taste and smell bad, and compounds that dry out your skin and hair. A softener removes hard water minerals that build up in your pipes and appliances causing them to prematurely fail. A reverse osmosis purifies basically everything. It filters down to an astonishing 0.0001 micron including viruses, bacterium, protozoa, chemical contaminants. (Cryptosporidium, Giardia, Campylobacter, Salmonella, Shigella, E. colI, Enteric, Hepatitis A, Norovirus, Rotavirus, sodium, chloride, copper, chromium, lead; may reduce arsenic, fluoride, radium, sulfate, calcium, magnesium, potassium, nitrate, and phosphorous)

  1. 1. Turn water off (any option will do)
    • Above the water heater on the right hand side is a water shut off
    • Shut off water at your mainline shut off typically in the garage or around the perimeter of your home
    • Lastly your water can be shut off at the street in the water box
  2. Turn the gas supply off
    • Typically your gas shut off will be yellow and is located towards the bottom
  3. Contain water and minimize damage
    • Get a bucket and towels to stop the water
    • Remove any wet belongings
  4. Give us a call
    • Call to discuss options and what to do next
