Yes, but you should watch the cost of fittings and plastic must be supported every two feet. Do not substitute fittings with Radiantec tubing. If you are using an open system, be sure that the materials are rated potable. All Radiantec polyethylene tubing is highly resistant to nearly everything. The reactivity charts show only a slight reaction to fuming nitric acid (above 1700° F)

First, a formulation review is performed on the material to determine what possible contaminants could leach out into drinking water and determines what type of chemical extraction testing is necessary. PEX tubing is tested by exposing the tubing to formulated exposure waters, and then analyzing the exposure waters for contaminants. Three separate formulated waters are used during the product exposure. A pH 5.0 and 10. See similar questions...

Yes, if your boiler is corrosion resistant and you use a stainless steel or bronze circulator pump and fittings, but the small additional cost for BPex is well worth the money. We recommend BPex or PAX tubing for all radiant systems. See similar questions...

Water exposed to PEX tubing and associated fitting systems are tested for the following contaminants as required by NSF/ANSI Standard 61: Regulated Metals scan including antimony, arsenic, barium, beryllium, cadmium, chromium, copper, lead, mercury, selenium, and thallium These test methods are capable of detecting contaminants in water as low as 4 parts per billion (4 ppb) and lower, equivalent to 0.0000004% concentration.

PEX tubing meeting the health effects requirements of NSF/ANSI Standard 61 will bear either the NSF-61 Mark or the NSF pw (potable water) Mark on the print string. The NSF pw Mark indicates the product meets the health requirements of NSF-61 as well as performance, long term strength and quality control requirements as required by NSF/ANSI Standard 14- Plastic Piping Components are Related Materials.

The mainline tubing can generally be buried with no problems. However, it is possible for burrowing rodents like gophers or moles to chew right through the line. That aside, it is often desirable to bury the line to have it out of the way so it won't be seen or tripped over. Emitter tubing can always be covered with mulch, which is, in fact, desirable to protect it from the sun and extend its lifespan. See similar questions...

The tubing can be wrapped around the pump and then the pump put inside the case or the tubing can be coiled along side the pump in the case or you can put the pump in the fabric case and simply tuck the tubing in however it fits. The case is worn on the side where the infusion set is inserted to avoid long sections of tubing hanging out. See similar questions...

PEX tubing was developed in the 1960s in Europe. PEX has been in use in many European countries for decades. In the 1980s, PEX tubing started to be used in the United States. Since that time, there has been a significant increase in both market demand and production of PEX in North America. [Back] See similar questions...

Unless the tubing has been kinked AND stretched, it's probably OK. If it's badly kinked though, the simplest and safest fix is to cut the kink out and crimp a coupler in its place. For the experienced professional plumber only, you can usually use a heat gun to reshape the tubing if needed, but be VERY careful with the heat gun, you can easily melt the tubing, burn yourself or start a fire if you're not very careful.

PEX is similar to PE that has undergone some additional physical changes. The "X" in PEX standards for cross linked. This means that PEX has additional links between the polymer chains. The additional links lend additional performance capabilities that ordinary PE does not have. The cross linking gives PEX tubing high performance capabilities at high operating pressures and temperatures of 160psi at 73F, 100psi at 180F, and 80psi at 200F (as noted for SDR 9 tubing in ASTM F876).

Ordinarily the radiant tubing must run at a lower temperature than the baseboard. This means that a mixing valve is used to provide a lower temperature for the radiant heating tube. It might be possible to avoid the expense of the mixing valve if the baseboard can be run at a lower temperature and if you select a radiant tubing with a high temperature rating, but the situation will not be ideal.

Yes you can, but keep the tubing away from the fixture and insulate the tubing in proximity of the fixture and follow manufacturers instructions. See similar questions...

For all hobbyists not involved in racing their car, the stock fuel line lengths are just fine. Fuel line length is commonly lengthened by several times the original length in order to prevent a flameout (engine dying) when the car is upside down. Racers sometimes use between 20-30cm (8 to 12 inches) of pressure line between the muffler or pipe and the fuel tank. This line must be wrapped around the fuel tank or another part of the car.

Rigid-wall, nylon tubing, 1/8" or 1/4" outer diameter. Believe it or not, Teflon, while inert, has a relatively high sorption for many compounds. The 1/8" nylon tubing is easier to work with than the 1/4" tubing if soil-gas sampling is your only need. If permeability testing is desired, the 1/4" tubing is better. Stainless-steel tubing is fine for shallow sampling but is logistically more difficult to install as the sampling depth increases (>5'). Flexible tubing (e.g. See similar questions...

The tubing is a double layer of metalized polyester film with a double inner layer of reinforced aluminum Sola-film with a highly reflective ultraviolet-proof laminate. The dome is made of UV Stabilized Grade-One Acrylic. By improving upon the flexible tube technology used for years in the heating and air-conditioning industries, we've created a way of bending sunlight around attic obstructions and the most cost- and-energy-efficient skylight system available in the United States.

PEX tubing is evaluated for conformance with standards for performance and health effects to protect the end user. Both the product manufacturer and independent third parties conduct routine quality control and quality assurance evaluations to ensure the product meets ASTM and NSF/ANSI Standards. Compliance with ASTM F 876 and F 877 as well as NSF/ANSI Standard 14 ensure the end user of safety and quality. [Back] See similar questions...

BPex is standard Pex that is manufactured with a special external coating that prevents available oxygen from permeating the tubing. Available oxygen in the water is what causes rust to form on ferrous radiant system components. We recommend BPex tubing for all radiant systems. If you use standard Pex tubing for your radiant system, instead of the recommended BPex tubing, you will need to install corrosion resistant system components (stainless steel, brass or bronze pump, boiler and fittings).

PEX and EXE ANSI Full Screen Editors seem to load in about the same amount of time. With different computers and processor speeds, your mileage may vary! PEX versions are easier to install but TheEdit seems to be the only PEX which has been very reliable in the past. EXE versions seem to be a lot more reliable than PEX versions, but unless you have a fast machine, they could take a little while to load. See similar questions...
