Should you use pipe insulation on PEX?
Yes, insulation is an essential part of installing PEX piping, as the lack thereof could lead to unfortunate outcomes. It is more resilient against fluctuations in temperatures than other commonly used materials. It's flexible pipes and does not act as a conductor for heat and cold as easily as metal materials do.
Will PEX water line freeze and burst?
PEX pipes, just like any pipe, can freeze when the temperature drops too low. Because the pipes are designed to be flexible, PEX has the ability to expand. Although it is still possible for them to burst, this means PEX pipes are less likely to rupture after freezing.
Should I insulate plastic water pipes?
Regardless of the type of plastic pipe used, insulation is essential. Plastic pipes have many advantages, but just like metal pipes they must be protected against energy loss. In refrigeration and air-conditioning applications they also must be protected against condensation.
What temperature will PEX freeze and burst?
How To Keep Pex Pipes From Freezing. Generally, if the temperature falls below 20 degrees Fahrenheit ice will form in water lines and pipes will freeze.
How do I insulate PEX water lines in my attic?
Foam Insulation It is important to insulate PEX pipe in an attic, particularly in cold-weather areas. Covering the pipe with lengths of foam insulation with adhesive seams will provide protection from the cold and heat while allowing the tubing to expand and contract.
Does PEX insulation better than copper?
PEX can also insulate water better than metal, which means hot water will lose less heat than it would in copper. PEX piping also doesn't suffer from scale buildup or chlorine damage the way copper can, and it can resist freezing conditions that would crack copper.
Is PEX pipe OK for hot water?
Color-Coded: Red PEX pipes can be used for hot water supply lines, blue PEX for cold water supply, and white for either hot or cold. These colors are just for your convenience. Plumbing code does not require the pipe color to match the type of water supply.
How cold can PEX pipe withstand?
"For similar material thickness, PEX is 68 times less conductive than copper, which can delay the freezing of fluids within PEX tubing, potentially preventing freeze events. In fact, PEX tubing remains flexible and can still be bent at temperatures below -40°F (-40°C).
What temperature is PEX pipe good for?
PEX does not melt (analogous to elastomers) and is thermally resistant. The maximum heat temperature of the PEX tube is 200 degrees. The maximum heat of the PEX can be up to 180 degrees. The PEX tubing has the highest temperature limitation listed in small prints.

How do you insulate PEX from freezing?
Below are a few tips when insulating PEX pipes:Use foam to insulate PEX pipes. Foam is the most popular insulation material for PEX pipes because they are flexible. ... Clean the pipes using a wet rag before wrapping them in foam.Seal the PEX tubes completely by using insulation tape on the foam insulation's ends.
Can you put heat tape on PEX?
To answer the main query, only use automatic thermostatically controlled heat tape on plastic water supply piping. Non-automatic heat tapes can potentially damage plastic pipes, particularly with taped lines with insulation (foam is commonly used for PEX, and vinyl insulation is occasionally used as well).
How do I insulate PEX water lines in my attic?

Why does Pex insulate?
He insulated the cold-water pex wherever he could, probably because it sits in a pressure tank and he was hoping it would stay cold. When you touch the cold and hot copper, you can feel cold and hot which means the heat transfer for copper tubing is efficient. (should insulate) Grab your pex and see what you can feel.
How long does cold water stay hot?
The water stays warm in the winter for about an hour. It stays hot for fifteen minutes. Without the insulation the water cooled in five minutes. Yes it is good to insulate the lines, as mentioned before, if the Cold water runs in unconditioned space or your condition space is kept at a higher humidity level.
What temperature is good for freezing water pipes?
So if you can get (like this year in Europe) a long term cold spell of -10°c to -20°c - pipe covering insulation (the grey foam type) is well worth it with regards to stopping freezing. Any insulation will prevent heat from transferring out of hot water pipes or into cold water pipes.
Is it worth it to run new pipes?
It's definitely worth it if you are running new pipes or the existing pipes are easily accessible, but if you have to lift boards etc. to gain access probably not.
Does a circuit setter have a hot water return line?
You may want to consider a circuit setter (like Circuit Solver) with a hot water return line so that hot water circulates (does not run to drain). The result will be that hot water is more quickly available. However, the circulation speeds up heat transfer out of the pipe, so insulating is still desirable. Share.
Does PEX Pipe Need To Be Insulated?
Yes, although PEX pipes can withstand freezing temperatures better than other pipe materials - but they are not freeze proof!
What Is The Best Insulation For PEX Pipe?
In our experience, we find that foam is a very good insulation product for PEX pipes. It's flexibile (like a PEX pipe is) and it does the job like any other insulating materials.
What type of PEX pipe is used for hot water?
Blue PEX pipe carries cold water. White PEX pipe can be used for either hot or cold water. Gray PEX pipe, like white, can be used for either hot or cold water (although not all DIY centers carry gray).
What type of fittings are used for PEX?
Hundreds of types of fittings, usually brass, are available for connecting PEX to existing copper or steel pipes, and for making connections to fixtures. Fittings are also available for connecting pipes of different sizes. The following five methods are used for making the connections watertight. Photo: amazon.com.
What is PEX tubing?
Choose the tubing best suited to your needs: PEX-A is manufactured using peroxide. This type of PEX is the most flexible of the three types and is suitable for use in all home water-supply plumbing needs.
What color is PEX?
Water flows silently through PEX, eliminating the “water hammer” noise associated with metal piping. Color-coding (red and blue) make it simple to distinguish hot and cold supply lines. PEX can be connected to existing metal supply lines with the correct fittings.
What is the advantage of PEX pipe?
PEX has a distinct advantage over these materials because of its flexibility, which allows one end of PEX pipe to connect to a PEX manifold (the main water control system) and then wind through walls and floors—uninterrupted—all the way to an individual fixture.
How long is a PEX pipe?
PEX is available in a variety of lengths, from short 10-foot pieces (for small repairs) to rolls over 500 feet long, which are used to install a home’s entire water supply system. PEX pipe ranges from 3/8- to 1-inch in diameter and its color-coding makes it a snap to identify what a specific pipe is used for. Although there are three types of PEX (see Label Lingo, below), the different colors don’t connote the distinctions; they simply make it easy for the installer to identify which lines carry hot water and which carry cold.
What is PEX pipe?
Cross-linked polyethylene (PEX), a type of flexible plastic, is currently replacing traditional copper and galvanized steel as water supply lines in both new construction and remodeling projects. You’ve probably seen rolls of blue and red PEX pipe in the plumbing aisle of your local home improvement store, but might not know that this colorful tubing now makes it possible for enthusiastic DIYers to replace their own leaky water lines instead of calling a pro. Read on to learn more about PEX—what it is, where it can be used, and all the pros and cons of this popular plumbing material.
Why is it important to insulate your water lines?
One of the biggest reasons used to promote insulating your lines is so that your hot water heater doesn’t have to work as hard &/or the hot water will arrive at your tap faster. Well I hate to say this but someone needs to study up on hydrodynamics. In order for hot water to arrive at the tap it basically must push all the water already in the line out.
How to prevent water lines from freezing?
To help prevent the water lines from freezing: In unconditioned areas make sure they are insulated, protected from drafts/ winds & if need be install heat tape. To help prevent condensation from forming on cold water lines: This is generally limited to very high humidity areas coupled with cold incoming well water.
How long does it take for a hot water line to reach ambient temperature?
The catch is that time period is limited. Just to use a simple example, let’s say that an uninsulated line reaches ambient (room) temperature in 10 – 15 minutes.
Is it going to happen if copper lines run through basements?
Yep it isn’t going to happen. Yes I do know where some people get this idea, and that is because they have copper lines that seemingly run for miles in their super cold basements. As the water is rushing through the lines it is giving up a bit of its heat.
Does insulating water pipes raise water temperature?
“Insulating your hot water pipes reduces heat loss and can raise water temperature 2ºF–4ºF. ” Really, just how exactly is a material made to help resist the flow of heat outward or inward magically going to heat the water aka raise its temperature? Yep it isn’t going to happen
