Everything you need to know to install plumbing at home.
Today many new houses are built. Many families prefer to buy land and build their own home tailored to their needs. That means there are going to be a lot of people looking to install plumbing in their new homes. Installing plumbing from scratch offers the opportunity to get it right.
When you are plumbing a home from scratch, it gives you the opportunity to take advantage of the latest technology and techniques. If you are planning to install plumbing in your new construction, here is what you need to know about plumbing a home under construction.
If you are building a new home or planning a major renovation project for an older home, you will want to take the time to think about the plumbing in the home. The laying of drinking water supply lines, sewer and drain pipes and plumbing vents should be installed in the right places with the shortest possible distances.
If you have a large home, the further the water connections are from the main supply line, the lower the pressure. Since it can be difficult to know if you will have enough water pressure after construction or renovation, it is a good idea to have a water pressure regulator installed at the same time.
The water pressure regulator will allow you to adjust the water pressure levels to fix any potential low water pressure problems without having to reconnect the pipes a second time. However, there is a word of caution with water pressure regulators. The plumber should always be asked to make adjustments to prevent pressure from being too high and damaging faucets and water appliances.
Plumbing in a newly built or renovation home
Plumbing has changed a lot since the turn of the century. Where pipes and plumbing fixtures were made of metal, today’s plumbing relies on a unique blend of modern plastics and alloys, for example.
That’s just one of the ways plumbing has evolved in the last 10 years. Building regulations have become much stricter. Building materials have also become very expensive, especially metals such as copper.
That means a plumbing mistake can be much more expensive than it used to be.
The parts of your home plumbing system
Plumbing systems have a lot of different parts and moving parts. Here is an overview of your new home’s plumbing system.
Clean water enters the plumbing system at 50 to 60 psi from the water supply line. Dirty water is pulled down by gravity to exit the plumbing system. The air blowing through the vents keeps the pipes clean and clear.
It’s a simple, self-contained system that should last the test of time if configured correctly.
Pounds per square inch, or psi, is the English unit of measurement for pressure. The pound serves as a measure of weight or force, and the square inch is a measure of area. Therefore, psi measures the amount of force in a given area, and force and area are inversely related. As strength increases, pressure increases, while area increases, pressure decreases.
If you are installing plumbing in new construction, you are going to want to install the plumbing fixtures before finishing the interior. Tubs, sinks, and showers are much easier to install when the walls and doors have not been installed yet.
Once you have installed the pipe fittings, they should be covered with cardboard or plastic to keep them clean and dust-free for the rest of the construction.
Septic tanks and sewer lines
Septic tanks and sewer lines are some of the trickiest parts of a home’s plumbing system. First, you will need to know what size septic tank you will need.
This is calculated based on the number of bedrooms in your new home.
Septic tanks separate solid waste from liquid waste. Inside the pit, facultative and anaerobic microorganisms help break down solid waste. This process creates gaseous by-products that must be properly vented.
You can already see that plumbing a home from scratch isn’t super complicated, but there are a lot of specifics you need to know. Now let’s take a look at a few things to consider for your new home’s plumbing system.
Things to consider when installing a plumbing system
While each building project is unique, with its own logistical considerations, these are some good rules of thumb to consider when you are ready to install your plumbing system.
Decide where the main stack will be
The main chimney is a pipe approximately 10 centimeters in diameter. It generally goes from the basement to the ceiling.
The lower part of the main sink collects the waste from the toilets. The middle part collects wastewater from other pipe fittings. The upper part is used for ventilation.
When you install the plumbing in your new home, you will need to find a location where the main fireplace can function without interruption.
Install your drains and vents
Drainage and ventilation pipes are usually 30 centimeters in diameter. The pipes must have a 1/4-by-30-centimeter slope to drain properly. The bends where the pipes meet the main pile should be smooth and not at a sharp angle.
Each appliance must have a siphon underneath. This siphon collects water and prevents harmful gases from entering the home.
Each appliance also needs to be ventilated. Installations located less than 1.5 meters from the main chimney may have “wet ventilation”. This means that there is enough room for both water and air to pass through.
Draw a diagram and get the permissions
You are going to need a building permit to install your plumbing. This requires a plumbing diagram. A plumbing diagram details all the drain pipes, vents, and pipe fittings in a three-dimensional drawing.
This diagram shows all pipe sizes, siphons, vents, and connection angles. The building inspector will use the diagram to ensure that the design is acceptable and the proposed construction is safe.
As you can see, there is a lot to know about installing a plumbing system. The principles are more or less the same as those used by the Romans, but the details have been much more nuanced.
By understanding how the different parts of your plumbing system work, you will be able to better assess problems and make more informed decisions about how to solve the problem.
