Drains can often become blocked, especially in areas of high human activity such as showers and sinks, and can require a licensed plumber to rectify.
In some cases, the use of a drain cleaner is sufficient in removing the blockage. Blocked drains, if left long enough, can be a high safety concern as the presence of Mold and bacteria increases.
Hot water repairs
Water is a convenient heat storage medium because it has a high specific heat capacity.
An efficiently insulated tank can retain stored heat for days, reducing fuel costs.
Hot water tanks may have a built-in gas or oil burner system, electric immersion heaters or heated water from another energy source.
Water heaters for washing, bathing, or laundry have thermostat controls to regulate the temperature and are connected to the domestic cold water supply.
Where the local water supply has a high content of dissolved minerals such as limestone, heating the water causes the minerals to precipitate in the tank (scaling). A tank may develop leaks due to corrosion after only a few years, a problem exacerbated by dissolved oxygen in the water which accelerates corrosion of both tank and fittings.
Leaking Tap Repairs
For baths and showers, mixer taps frequently incorporate some sort of pressure balancing feature so that the hot/cold mixture ratio will not be affected by transient changes in the pressure of one or other of the supplies. This helps avoid scalding or uncomfortable chilling as other water loads occur (such as the flushing of a toilet).
Rather than two separate valves, mixer taps frequently use a single, more complex, valve controlled by a single handle (single handle mixer). The handle moves up and down to control the amount of water flow and from side to side to control the temperature of the water. Especially for baths and showers, the latest designs are thermostatic mixing valves that do this using a built-in thermostat and can be mechanical or electronic. There are also taps with colour LEDs to show the temperature of the water.
Seals over time become degraded and need replacing.

Gas fitting is defined as any work on a connection to a gas installation. It includes work on pipes and other connections to a compressed gas source, whether it’s a gas cylinder or natural gas supply. Because of the danger posed by gas, gasfitters must be licensed professionals.
You may need to employ a licensed gas fitter to connect a number of home appliances, including:
Gas air conditioners
Gas hot water systems
Bacteria have been shown to live in "premises plumbing systems". The latter refers to the "pipes and fixtures within a building that transport water to taps after it is delivered by the utility" Community water systems have been known for centuries to spread waterborne diseases like typhoid and cholera. However, "opportunistic premises plumbing pathogens" have been recognized only more recently: Legionella pneumophila, discovered in 1976, Mycobacterium avium, and Pseudomonas aeruginosa are the most commonly tracked bacteria, which people with depressed immunity can inhale or ingest and may become infected with. Some of the locations where these opportunistic pathogens can grow include faucets, shower heads, water heaters and along pipe walls. Reasons that favour their growth are "high surface-to-volume ratio, intermittent stagnation, low disinfectant residual, and warming cycles". A high surface-to-volume ratio, i.e. a relatively large surface area allows the bacteria to form a biofilm, which protects them from disinfection.
