What is PEX

• PEX was developed in the 1960’s

in Germany and has been used in

plumbing applications for over 30

years in Europe

• Through one of three processes,

©


• Through one of three processes,

High Density Polyethylene

undergoes a change to produce a

three dimensional link.

• This makes PEX stable for higher

temperature applications such as

plumbing and radiant heating.

• Implementation January 4, 2014

Amends the Safe Drinking Water Act

New ZERO LEAD Requirements

Amends the Safe Drinking Water Act

The amended definition of “lead free” is provided

• 0.20% max lead for solder and flux

• 0.25% max lead for products by weighted average

• Multiple component products are calculated to address total

wetted exposure based upon wetted surface area of each

component and that component’s lead content by percentage

PEX Tubing Installation Practices

Water Heaters and Other Heat Sources

• DO NOT connect directly to gas fired hot water heater

• Check With Local Codes Regarding Connecting To Gas Water Heaters

©


Maintain a minimum of

6 inches of clearance

from gas heater vents

Minimum of 12 inches of vertical heat sources like

recessed lights and appliance or heater vents

PEX Tubing Installation Practices

Concrete Installation

• Use plastic elbow sleeves when exiting slab

• Protect tubing via sleeving

when passing through

expansion joints

©


• Fasten tubing every 2-3 feet to

wire mesh

• Protect the PEX tubing with

non-metallic sleeving material

where it enters and/or exits a

slab. (PEX need not be

sleeved its entire length.)

Water Hammer, Grounding, Pressure Testing

Water Hammer

• PEX tubing reduces the tendency for water hammers, and

helps prevent damage that might be caused by these

pressure changes.

• Arrestors are still advisable in situations where rapid flow

stoppage may occur or when required by code

Grounding

©


Grounding

• Neither PEX nor aluminum PEX products may be used as

electrical ground

Pressure Testing

• The system must be pressure tested in accordance with

local codes or at least at working pressure (within tubing

limits)

Home Run System Piping Design

How Does The Home Run System Work?

• It’s uses a centrally located

manifold with individual

shut-off valves to supply

each fixture with dedicated

distribution lines.

• PEX distribution lines run to

©


• PEX distribution lines run to

each fixture in a “home-run”

system.

• A large reservoir in each

side of the manifold helps

maintain equal pressure

• Appropriately-sized lines can be installed so hot water is delivered faster. (3/8” and 1/2”)

• Less water is wasted while purging

How Does the Home Run System Work?

©


• Less water is wasted while purging these lines.

• Reduce water and energy waste by up to 40%

• By providing each fixture with its own distribution line, the system out-performs conventional plumbing designs.
