Why do we use Copper pipes and not plastic when possible?
Archaeologists have recovered a portion of a water plumbing system from the pyramid of Cheops in Egypt. The copper tubing used was found in serviceable condition after more than 5000 years.

Superior flow rates as larger internal diameter increases flow rate.
Copper fittings are on the outside of the tube. Most plastics and composite tube fittings are inserted into the pipe resulting in restricted flow.
Can Withstand High Temperatures and Pressure
Copper tube can handle temperatures and pressures several time greater than plastic.


UV Resistant
Anti - Microbial Properties
Scientific studies are underway to prove that copper plumbing keeps drinking water clean by keeping down microbial growth.

Copper is Biostatic
Inhibits bacterial growth.

Not Permeable
Copper does not absorb organic materials. Possible contaminants cannot penetrate copper.

Fire Resistant
Very fire resistant, high melting point.
No Toxic Fumes in Fires
Copper does not give off toxic gasses when exposed to fire.

Plastic pipe agents generally do not take responsibility for material failures with little or no after sales service.

Geyser repairs - Common faults
Maintenance Pertaining to the Geyser one of the common problems associated with a geyser is that client experiences little or no hot water. No hot water or little hot water could be result of the following:
Partial/complete failure of the thermostat
Partial/ complete failure of the element
High water usage (additional guest)
Undersized element for geyser
Undersized geyser
Hot water displacement within the geyser due to sediment build up
Thermostat setting low / thermostat calibration is faulty
Power failure or ripple relays activated
Electrical (wiring/circuit breakers) faulty
Undetected hot water pipe leaking
Hot water taps leaking
Un-lagged pipes or long dead legs of the hot water pipes
Hot water discharged from the T&P valve
Geyser repairs - Basic info
A domestic electrical geyser typically has an element of 2000 watts to 4000 watts coupled with a thermostat to heat the water.

Burst pipes - Why do pipes burst?
Burst pipes occur when the integrity of the pipe wall is breached. There are 2 x main reasons burst pipes occur.
1. As temperatures near freezing point, the water in the pipe expands. When this expansion occurs in a confined environment such as a water pipe, there could be substantial pressure placed on the inner walls of the pipe material, whether it be Copper, Iron or Plastic pipes. When the pressure in the pipes increases rapidly and exceeds the rating of the pipe a burst pipe will occur.
2. Corrosion in the pipes causes the pipe wall diameter to decrease and results in the weakening of a pipe. When pressure spike occur this could lead to a burst pipe.
Burst pipes are repaired by replacing the affected section with a new piece of pipe, this could result in walls that have to be chopped open for access. DrainCorp plumbers will repair burst pipes in your home, office or factory.
What causes water leaks?
Water leaks occur due to various reasons including water chemistry, the pH of the water, the temperature of the water, Oxygen levels in the water, water pressure and velocity of water in the pipe. In South Africa chemistry causes most of the pipe failures. Galvanic action occurs when Copper pipe and Galvanized pipe are joined incorrectly, causing rapid degradation of the pipe. DrainCorp plumbers will repair any water leaks.
