The Science Of Plumbing

The physical law of water it that it will always find its level spot. And when paired with the law of gravity and the law of pressure, it can invade your home, thus invade your wallet. It is all based on how you, the homeowner, maintains, prepare, and reacts to plumbing.

There are two ways that plumbing systems work: water coming in and water going out. More concisely, clean water comes in, dirty water goes out. When those two mixes, that’s when you have problems. And that is when you need a professional.

How Clean Water Enters

Clean water enters your home following the law of pressure which permits it to pass through the pipes and travel upwards. The law of pressure allows it to rise up from the ground, to one floor or more, and move to the left or right, wherever it is needed. Those pervasive water valves in your home, aka, the faucets and knobs, control how that pressurized water moves into and around your home.

The main water supply supplies cold water to your home through that process. You get hot water from the water heater that heats that cold water first and then sends it to whichever faucet you’ve turned the hot water knob on, like a bathtub or sink.

The Simplicity in Science of Plumbing

The intake of water is simple science as is the outgoing water aka waste water. Frequently, it is the waste water going out that causes plumbing problems and can cause expensive repairs. Waste water leaves the home by the law of gravity, flowing downward toward the sewer.

The placement of multiple traps and vents keep the downward flow going as it allows air into the pipes, forcing the water out. The s-curves in the pipe are traps that force the water downward, but allow some water to stay behind and seal the pipe, keeping sewer gas out.

Ignoring the Science of Plumbing Can Be Costly

The science of plumbing is more important than just passing eighth-grade. It is the basics of that science that comes to light for a homeowner when the bathtub won’t drain or the toilet overflows. By ignoring that basic science, your home could flood, causing extensive damage to be repaired, which becomes costly.

While there are some plumbing matters in the home that can be taken care by the homeowner, when the problem is of a larger nature and causing, or could cause, major damage, the experience and knowledge of a professional plumber is needed.


For example, a toilet overflowing can often be remedied by using a household plunger. A clogged drain can sometimes be remedied by using a household plunger. However, if the back-up, slow to drain continues, it may need more attention further into the pipes than what the plunger can affect.  Such as a plumbing snake or even the need to have pipes replaced.  It is in those instances, calling in a professional is recommended.
