Standard hot water tanks will bush down to 3/4″ even though you may have a hot water supply demand that requires a 1″. You won’t have the volume of water that you need to run the fixtures correctly.
In respect to this, can I use CPVC pipe for hot water heater?
Tank-Style Water Heaters
CPVC piping is rated for hot water heater installation, we highly recommend talking with a professional plumber before replacing the water inlet and outlet lines with CPVC or PVC. … These lines are often made of copper, but this is an excellent use for schedule 40 CPVC piping.
Keeping this in view, how do I calculate plumbing pipe size?
1 inch= 25.4mm, 1 ft. = 304.8mm, 1 gallon/m=3.785L/m. Water velocity should not be greater than 2.438m/s at valve seat to prevent noise and erosion. So, Pipe area should be at least equal to water flow rate divided by eight.
How do I choose a pipe size?
The equation for pipe diameter is the square root of 4 times the flow rate divided by pi times velocity. For example, given a flow rate of 1,000 inches per second and a velocity of 40 cubic inches per second, the diameter would be the square root of 1000 times 4 divided by 3.14 times 40 or 5.64 inches.
How do I know what size pipe I have?
To find it, measure around the circumference of the pipe with flexible measuring tape. Divide the circumference by pi, or about 3.14159. For example, if the circumference is 12.57 inches (319 mm), you would divide by pi, and get an outside diameter of about 4 inches (100 mm).
How do you size a hot water line?
Is copper pipe good for water?
Copper has natural qualities that make it ideal for plumbing. It is extremely durable. It creates a biostatic atmosphere, which makes it difficult for bacteria to grow inside of it. It also resists corrosion and it is not affected by ultraviolet rays, which allows you to use it outside.
Is it OK to use PVC pipe for hot water?
The short answer: No. Explanation: PVC is a thermoplastic, and therefore, at some point it will begin to degrade and break down as it’s heated up. It just so happens that Schedule 40 PVC’s maximum operating temperature is 140 degrees Fahrenheit, around the same temperature that hot water gets to in most homes.
What is a PEX water line?
PEX, short for cross-linked polyethylene, is a flexible plastic used for plumbing. The tubing has become quite popular over the years, replacing traditional copper and galvanized steel water supply lines.
What is the difference between Type M and Type L copper pipe?
The Differences between Types L and M
The key difference between types L and M is their pressure rating and wall thickness. The most common copper pipe sizes are ½ and ¾ inches. Type M ½ inch measures 0.028” in wall thickness whereas type L ½ inch measures 0.04” in wall thickness.
What is the standard copper pipe size?
Sizes
| Copper Tubing Sizes (CTS) for Plumbing | ||
|---|---|---|
| Nominal size | Outside diameter (OD) [in (mm)] | Inside diameter (ID) [in (mm)] |
| 3⁄4 | 7⁄8 (22.225) | 0.785 (19.939) |
| 1 | 11⁄8 (28.575) | 1.025 (26.035) |

What is the standard water pipe size?
What size is water heater copper pipe?
In some areas, Type M pipe isn’t allowed for delivering potable water, but it can be used for hot-water heating systems. Copper pipe is commonly available in diameters ranging from ½ inch to 2 inches.
What type of pipe is used for water heaters?
With good resistance to both hot and cold temperatures, PEX is commonly used for both hot and cold water lines in homes, and for hydronic heating systems (such as radiant under-floor systems). PEX is considered more durable than copper, with a likely lifespan of more than 50 years.
