The difference between pipes and tubes is simply in the way it is sized.
These sizing schemes allow for universal adaptation of transitional fittings.
1/2" PVC on the other hand is not the same size as 1/2" tubing, and therefore requires either a threaded male or female adapter to connect them.
The temper of the copper, that is whether it is a rigid "joint" or flexible roll, does not affect the sizing.7 The thicknesses of the water pipe and tube walls can vary.
Pipe wall thickness increases with schedule, and is available in schedules 20, 40, 80, and higher in special cases.The schedule is largely determined by the operating pressure of the system, with higher pressures commanding greater thickness. Copper tubing is available in four wall thicknesses: type DWV (thinnest wall; only allowed as drain pipe per UPC), type 'M' (thin; typically only allowed as drain pipe by IPC code), type 'L' (thicker, standard duty for water lines and water service), and type 'K' (thickest, typically used underground between the main and the meter). Because piping and tubing are commodities, having a greater wall thickness implies higher initial cost.
Thicker walled pipe generally implies greater durability and higher pressure tolerances. Wall thickness does not affect pipe or tubing size.8 1/2" L copper has the same outer diameter as 1/2" K or M copper.
As a result, a slight increase in pressure losses is realized due to a decrease in flowpath as wall thickness is increased.
These include the repair of the broken washing machine and a dripping faucet.The problem with a broken washing machine happens to its owner very troublesome, because the water leaking from the machine may flood the entire bathroom or the finished washing remove it clothes, which is a powder. In such a situation as soon as we call for help to the plumber. Equally often we call a plumber to repair a leaky faucet.
Sometimes it turns out that you need to replace it, only the gasket, and another time the culprit turns out to be defective cam.Normally, we release a new cam will be covered.
We will have to pay only for services rendered by the plumber..
