Polyvinyl chloride was discovered late in the nineteenth century. Scientists observing the newly created chemical gas, vinyl chloride, also discovered that when the gas was exposed to sunlight, it underwent a chemical reaction (now recognized as polymerization) resulting in an off-white solid material. But, the solid material was so difficult to work with that it was cast aside in favor of other materials. Years later in the 1920's, rubber scientist Waldo Semon was hired by BFGoodrich to develop a synthetic rubber to replace increasingly costly natural rubber. His experiments eventually produced polyvinyl chloride. Although product developers began to use PVC in a variety of ways – in shoe heels, golf balls, and raincoats, to name just a few – its application increased significantly during World War II.
PVC turned out to be an excellent replacement for rubber insulation in wiring and was used extensively on U.S. military ships. After 1945, its peace-time usage exploded.
In the U.S., PVC's materials are natural gas and rock salt.
Natural gas is heated under pressure to form ethylene. This is called "cracking".
Common rock salt (sodium chloride) is split by electrolysis to produce chlorine and lye (sodium hydroxide).
Chlorine and ethylene are combined to form vinyl chloride monomer (VCM).
VCM molecules are then joined end-to-end (polymerized) to form long chains of Polyvinyl Chloride polymer (plastic).
The thermoplastic PVC powder is compounded, melted and extruded into pipes.
Low Water Pressure
If you're experiencing a decrease in water pressure at your property, the issue is typically within your plumbing system. The list below may help you identify the cause of the low pressure at your property.
In many cases, the cause of a sudden change or decrease in home water pressure is the result of a water softener. If it has been a while since your water softener was serviced, you may want to consider having a professional service technician evaluate your water softener condition.
Depending on the type of water softener and plumbing configuration at your property, you may be able to troubleshoot low-pressure issues caused by your water softener. One option is to temporarily put the softener on bypass and see if pressure increases. If it does, the low pressure is probably caused by the water softener and it may need to be serviced or possibly replaced.
Pressure Reducing Valve
If the low pressure is at every faucet in the home and you have a pressure reducing valve (PRV) installed on your home plumbing system, you may want to verify that your PRV is set appropriately. Most PRVs are bell-shaped devices that may be installed near the water heater, water softener or outside on the inlet water line between your home and water meter. PRVs should be adjusted by a certified plumber.
If the low pressure is not affecting every faucet, the problem may just be a clogged or blocked faucet aerator. Check the aerator screens for rust, debris, scale or other particles that may be restricting flow. Simply clean or replace the aerator altogether.
Hot Water, Low Pressure
If the low pressure is only affecting the hot water at your property, there could be a problem with your water heater. Check the shut-off valve near the water heater and make sure it is fully open. You may need to consult a certified plumber to evaluate the condition of your water heater and determine if it is affecting your water pressure.
On-site Water Valve
Most homes in Southern Nevada have an on-site water valve located near other on-site fixtures, like a water heater or water softener. The valve may also be located in the garage or on the inlet line between your home and water meter. This valve, which may be utilized to make plumbing repairs, allows you to shut off the flow of water to the home. Make certain that this valve is open completely; even the slightest closure can restrict flows and decrease the water pressure.
Low pressure also can be caused by a water leak somewhere on the property
EL TAPONAMIENTO DE TUBERÍAS ES MUY FRECUENTE, ALGUNOS DATOS SOBRE ESTO:
Una de las razones principales por la que se tapan las tuberías es por el mal uso, tal como, botar la grasa o el aceite de cocinar por la tubería y peor aún el uso del triturador de desperdicios.
El triturador de desperdicios es el mayor causante de que se tapen las tuberías. Si las personas fueran más cuidadosas con el uso de las tuberías se evitarían muchos dolores de cabeza. Pero en el caso de que su tubería ya esté tapada o tenga acumulación, hay solución para su problema.
No todo el que tenga una máquina de destapar sabe o entiende como se debe de utilizar eficazmente para que no solamente destapen la obstrucción si no que limpien la tubería para que ésta no se vuelva a tapar en 6 meses o un año.
Hoy en día hay más tecnología para destapar y limpiar las tuberías. Cuando se utiliza la máquina común de destapar que tienen todos los plomeros solamente se está destapando la tubería pero no se está limpiando.
Si la tubería solo se destapa y no se limpia, la acumulación de los desperdicios que están pegados a las paredes de la tubería causará que la tubería se tape frecuentemente causándole un gasto a usted innecesario de cada 6 meses a un año.
Con la máquina Hydro Jetter para destapar y limpiar las tuberías con agua a presión, usted tendrá la tubería tan limpia como cuando la casa fue construida de nueva.
Esta máquina limpia las paredes de la tubería utilizando agua, no químicos que dañan las tuberías permanentemente. De igual forma con presurizado de tuberías obtenemos el mismo resultado eficiente a la hora de destapar.
