To provide a water supply, you must use underground plumbing, commonly referred to as “p-trap” pipe. Usually found in homes that have wells, these pipes pull fresh water into the house where it can be turned on for household use. In order to make sure this system is weatherproof, a number of precautions are required: insulation, concrete crack fillers, and outdoor grade tubing.
Installing an underground pex pipe-
If you are looking to install an underground pex pipe, be sure to consider the installation and associated risks of insulation. Insulation can significantly increase the cost of a project as well as increase the required drill time. While installation of underground PEX pipe without insulation may be possible in some cases, it is generally not recommended due to potential risks. If you are uncertain whether or not insulation is required for your project, consult an experienced contractor.
What to do before you install an underground pex pipe-
If you’re considering installing underground PEX pipe, be sure to read up on the insulation options first! Once you know what kind of insulation is best for your situation, make sure to ask your contractor about it. Before you begin the process of installing underground pex pipe, consider these few things:
1. Measure your home’s temperature: Underground pex piping typically needs a bit more insulation than piping installed on the surface. To be safe, measure the temperature inside your home at different points and plan your insulation installation based on that information.
2. Insulate your property: Before you start digging, make sure to insulate all of the wooden surfaces within 10 feet of the proposed pipe location—this includes framing, siding, and decks. For detailed instructions on how to do this, consult with a contractor.
3. Obtain permits: Prior to starting any construction, consult with your local building department to ensure that you’re following all applicable codes. Permit fees can add up quickly, so be prepared to pay up front!
If you’ve read through these tips and are still unsure whether installing underground pex pipe is right for your home, consult with a contractor first. They’re familiar with all types of underground piping and should be able to tell you whether or not underground PVC pipe is the right solution for your home. Whether installing underground pex pipe will solve drainage issues in your home or not, it’s always a worthwhile investment. This type of pipe is ideal for crawlspaces, basements, and garages.
Types of piping that can be buried underground-
Underground piping can be of a variety of materials and construction types, but one common type is poured-in-place (PIP) pipe. A PIP pipe is made of a plastic or metal casing that is filled with concrete and then sealed. Because PIP pipe is lightweight, it’s often used in locations where excavation or heavy lifting would be difficult or expensive.
One downside to PIP pipe is that it doesn’t have insulation. This means that if your building’s heating and cooling systems use water as their main ingredient, heat will travel through the piping more easily in cold weather and less easily in warm weather.
There are two main types of insulation for underground piping: mineral wool insulation and foam insulation. Mineral wool insulation is the most traditional type of insulation, and it creates a very tight seal with the surrounding soil. Foam insulation, on the other hand, is less effective at sealing the piping and doesn’t create as tight a fit with the soil.
Depending on the type of insulation you choose, there are a couple of ways to address this issue. One option is to install a thermal envelope around the piping; this will create an airtight seal. Another option is to install a vapour barrier around the piping; this will create an airtight seal along with providing vapour control in winter.
Types of insulation materials for pipes and fittings.
There are a few types of insulation materials which can be used for underground piping systems, each with its own advantages and disadvantages. Here is a summary of the most common types:
1. Polyurethane foam (PUF) is a popular insulation material for cold-weather piping systems because it is inexpensive, easy to install, and offers good thermal insulation properties. However, PUF does not stretch or deform under pressure, so it may not be the best choice for applications where high intracranial pressure is likely.
2. Fiberglass batts are another popular insulation material for underground piping systems because they are lightweight and offer good resistance to fire. Unlike PUF, fiberglass batts do not compress significantly under pressure, so they may not be ideal for applications where large amounts of water flow through the system. Also, fiberglass batts can trap moisture between the batts, which can lead to corrosion and joint failure over time.
3. Cellulose insulation is a high- performance insulation material that offers excellent resistance to fire and moisture vaporization. However, cellulose insulation is bulky and difficult to move around, so it may not be the best choice for applications that need cross venting or unrestricted access to the crawlspace. Cellulose insulation can be removed and reused, which adds to its cost over time.
What do I need to know on the job site?
Installing underground PEX pipe requires proper insulation. In most cases, an R-value of at least 9 is required. A properly installed PEX system will also require a sealant between the pipe and the surrounding soil or concrete.
