In any case, whatever your plumbing situation is, before you decide to hire a plumber, it’s a good idea to have a basic understanding of how the plumbing in your home functions. Equipped with this knowledge, you’ll be able to talk to your plumber in an informed way. This would put you in a good position for making decisions, and it’ll help you to understand what the plumber is able to do.
In your house, there are basically two plumbing systems—the inbound, as well as the outgoing. When you look at the exposed pipes within your basement or closets, there’s an excellent chance that you’re looking at both incoming as well as outgoing pipes. In many cases, you can’t tell them apart just on sight. However, in their functioning, they will never cross.
While each of these systems don’t essentially contact each other, they do depend upon the other for their existence, and there is no plumbing fixture that is not connected with both sides. Therefore, when a plumber, works in your home, you can expect him or her to work with either side of the system.
Plumbing relies upon two essential forces of nature—pressure and gravity. When the water leaves the treatment plant, it goes into the internal system with incredible force—enough force, as a matter of fact, that it reaches your home with a great deal of pressure remaining. So, when you turn on your faucet and the water gushes out, it’s not because there is a piece of equipment somewhere within the house that gives it this pressure. That pressure can be traced all the way back to the water plant.
On the outgoing side, your water system relies upon gravity. Through your toilet, bathtub, and sink drains, the water stays on a consistent downhill plane all the way to its final location. And if you’re interested by that S-shaped pipe under your sink, the explanation is simple: This S is designed to catch water and hold it so that drainage gases are blocked from returning through your drain.
When water is supplied into your house, it’s already cold. When it comes from your tap lukewarm, this is due to the fact the water that originally comes out has been sitting in the pipes in your walls, which bring the water up to room temperature. Hot water is diverted from the cold water pipe, sent from a hot water heater, and warmed with electricity or gas.
