Homes have many combustion appliances, such as stoves, water heaters, fireplaces, furnaces, and boilers. Without proper ventilation, these appliances can create harmful gases such as carbon monoxide. Adequate ventilation is absolutely necessary in any home. For example, exhaust fans can play a pivotal role in clearing out harmful gases in bathrooms, cooking areas, and garages. They can keep the air clear of harmful moisture and fumes, while increasing your comfort by keeping humidity levels low.
Plumbing originated during ancient civilizations such as the Greek, Roman, Persian, Indian, and Chinese cities as they developed public baths and needed to provide potable water and wastewater removal, for larger numbers of people. Standardized earthen plumbing pipes with broad flanges making use of asphalt for preventing leakages appeared in the urban settlements of the Indus Valley Civilization by 2700 BC. The Romans used lead pipe inscriptions to prevent water theft. The word "plumber" dates from the Roman Empire. The Latin for lead is plumbum. Roman roofs used lead in conduits and drain pipes and some were also covered with lead. Lead was also used for piping and for making baths.
“Don’t go to the Yellow Pages to find a plumber,” says Berkey’s Bill Stevens. “It’s like guessing lottery numbers. Anyone can make an appealing ad, but that doesn’t mean they are legitimate. In this industry, it’s easy for a plumber who develops a poor reputation to advertise under a different name. They come and go.” Even searching for someone online may end up being a scam using fake reviews. Instead, look for a plumber who is well-established in your community. Check the Better Business Bureau and read customer reviews at sites such as HomeAdvisor, Angie’s List, or Citysearch. Local contractors or plumbing fixture stores can also refer you to a quality plumber, according to Grady Daniel, who owns a plumbing company in Austin, Texas. “Most of these firms won’t work with bad plumbers.” Or simply ask your neighbors for a referral. A trusted plumber that consistently delivers quality service does not remain a secret for very long.
