What is the flow rate of 1 2 PEX?

At a design velocity of 8 feet per second (fps) in a ½” PEX system, water velocity will reach at least 12.7 fps and as high as 19 fps, depending on the type of fitting used.

What is the ID of 1/2 PEX?

3) 5/8 in. tubing is better than 1/2 in. tubing.

PEX Tubing Size Information
Nominal ID OD Avg. ID
1/2″ 0.625 0.475
5/8″ 0.750 0.574
3/4″ 0.875 0.681

What size PEX pipe should I use on my house?

PEX tubes range in diameter from 3/8-inch to 1-inch for residential applications. For adequate water flow, it’s a good idea to install 1/2-inch or 3/4-inch PEX for your main lines. The standard when replacing old water supply lines with PEX is to use the same size.

Is PEX smaller than copper?

While PEX tubing has a smaller inside diameter than copper tubing, both tubing systems meet the farthest fixture demand, even with multiple fixtures flowing.

Do 90 degree fittings restrict water flow?

yes 90 degree bends restrict the flow, no matter if you are using high flow or low flow. If you cant avoid using bends, go to the hardware store and get some copper pipe bends, they have an easier more sloping bend to them then the acrylic ones.

Is it OK to use blue PEX for hot water?

It is usually not approved for use with potable water. There would be no problem, for example, using blue PEX for hot water lines or red PEX for cold water lines. Other types of PEX include PEX-Aluminum-PEX, which is often orange, and PEX for reclaimed water, which is usually purple.

Should I use PEX or copper?

PEX pipe is not only cheaper than copper but more durable too. PEX is immune to corrosion and mineral build-up, and it’s not affected by electrolysis, which can cause small pinhole leaks in copper piping. Copper pipes can last anywhere from six months to the life of a building.

Can you use orange PEX for drinking water?

SharkBite PEX Tubing is an excellent flexible water pipe tubing product for plumbing, radiant, and hydronic systems. Designed for use on hot and cold potable water lines, Orange PEX tubing is commonly used for radiant floor and hydronic heating applications.

Do I need oxygen barrier PEX?

PEX without an oxygen barrier actually allows oxygen from the air to permeate it. This happens even if the PEX is embedded in concrete. Cast iron circulator pumps will rust when oxygen is present in the water. Bronze or stainless steel circulators are necessary when this is the case.

Is PEX better than PVC?

When a connection to copper or other metal pipes is required, PEX works better than PVC because crosslinked polyethylene won’t corrode. It’s resistant to freezing (once again, due to its flexibility, which allows the PEX piping’s diameter to expand as the water pressure changes).

Can you bury PEX water line?

PEX tubing is approved for direct burial outdoors, a practice most often necessary when running a water supply line to a house. PEX, since it can expand, resists freezing more effectively than rigid pipe, but PEX can still burst if water freezes in a line. Embedding PEX in sand protects it from any rocks in the soil.
