Plumbing - what a valve is?

A valve is a device that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways. Valves are technically fittings, but are usually discussed as a separate category. In an open valve, fluid flows in a direction from higher pressure to lower pressure. The word is derived from the Latin valva, the moving part of a door, in turn from volvere, to turn, roll.

The simplest, and very ancient, valve is simply a freely hinged flap which drops to obstruct fluid (gas or liquid) flow in one direction, but is pushed open by flow in the opposite direction. This is called a check valve, as it prevents or "checks" the flow in one direction. Modern control valves may regulate pressure or flow downstream and operate on sophisticated automation systems.

Determining the cost of water consumption

Professional installation of water meter may take a plumber. It will be able not only to assume, but also seal the counter in such a way that the reading will be error. This will allow precise determination of the amount of water used in the household and issuing the appropriate invoices, that will not in any way overpriced. At the same time plumber will be able to advise the owners of the visited household, how they can reduce the costs associated with the amount of water consumed. At the request will also be able to check whether at home, there is no leakage and no need to replace any seals. Besides a good plumber can recommend the purchase of such sanitary facilities that allow you to save water.


Plastic pipes - some facts

Plastic pipework is used for the conveyance of drinking water, waste water, chemicals, heating fluid and cooling fluids, foodstuffs, ultra-pure liquids, slurries, gases, compressed air and vacuum system applications.

Plastic pipe systems fulfil a wide variety of service requirements. Product standards for plastics pipe systems are prepared within the standards committee known as CEN/TC155. These requirements are precisely described in a complete set of European Product Standards for each application alongside their specific characteristics.

For example:

Conveyance of drinking water: Hygienic requirements

Conveyance of gas: Highest Safety requirements

Plastic pipes for radiant heating and floor heating: Temperature resistance over decades

Sewer applications: High chemical resistance.

Plastic pipes are perfectly capable of fulfilling the specific requirement for each application. They do so with a high level of performance over a long lifetime and with reliability and safety.

The key factor for success is achieved by maintaining consistently high quality levels. For plastic pipe products, these levels are closely defined by the different standards.
