Application guidelines for Flexible PVC pipe:

All white Flexible PVC pipe we sell meets applicable UPC, USPC, ANSI, IAMPO, and NSF specifications, as well as City of LA, Southern Building Code, and Dade County, but not for potable water. Gray in sizes 1/2" to 2" has a UL rating for electrical conduit, but black has no ratings other than for swimming pools. It's all the same pipe, but because of the different uses, not all have the same rating. Flexible PVC pipe should be used in accordance with the following guidelines:

  1. NEVER to be used where there is a constant "dead head" pressure. ie, There should normally be a flow of fluid through the pipe. The pressure ratings given are for flowing pressure situations. Typical okay uses are: swimming pools, spas, hottubs, whirlpool bathtubs, irrigation (after the valve), ponds, drainage, conduit, suction applications, etc. As long as there is flow in the pipe you should be fine within the rated specifications.

  2. Should not be used with "booster pumps" applications. Ie, two pumps in series. In such situations, the flow stops and then starts repeatedly, it produces a "hydraulic hammer" effect and the glue joints may eventually fail. Standard swimming pool pumps are fine, booster pumps in addition to a standard pump are not. Note: the pipe itself rarely fails. In fact, we've never seen the pipe burst, but the fitting connection is where it will fail. Also if the pipe is buried in the ground with sharp rocks, sometimes the rocks can rub a whole in the pipe. Keep this in mind when burying pipe.

  3. While white FlexPVC does have an NSF rating, it is not suitable for potable (drinking) water applications. There is nothing toxic in the pipe, but it will pick up a "plastic taste" if water sits in it for several hours. This is the only reason it doesn't have a potable water rating: it can't pass the taste test. Same for black or gray. Neither can be used for potable drinking water.

  4. It is not resistant to insects, in particular, termites have been known to eat it. Research has shown flexible PVC does not attract termites, however if flexible pvc is placed in between a termite nest and a food source, they may try to eat their way through it. FlexPVC.com will not be responsible for failure due to insect damage, nor rocks rubbing against the pipe and wearing a hole in it. You can lace your backfill and trenches with boric acid to reduce the likelyhood of termites, but it won't last forever. If you have termite infestation and want to use Flexible PVC pipe, you should retreat your trenches every few years to be safe, just like you do your house, garage, etc.

  5. When is "schedule 40" not schedule 40? Our flexible PVC is treated as a hose by the building industry, not a pipe. Thus our hose fits Schedule 40 fittings (dimensionally) and can be used in place of schedule 40 pipe for many applications, but it does not meet all the requirements for schedule 40 pipe. (If you look at the specification on the Specs Page you will see the pressure ratings are not the same as schedule 40 pipe.) So, while we call it "flexible pvc pipe" in reality it's a hose that fits perfectly into schedule 40 fittings, but it can't meet the most stringent "schedule 40 pipe" requirements.

  6. FlexPVC is not suitable as a flue for furnaces or heaters. The high heat causes the pipe to become soft and will collapse upon itself, possibly causing a kink in the pipe and then obstructing the airway.

  7. If you are using it for something other than water movement, see our chemical ratings chart (png) or chemical ratings chart (tif). An "A" rating means you can use it without damage to the pipe. A "B" rating means you can use it, but over time the pipe will be effected. A "C" rating means you should not use it with that chemical. In all cases the chemical is concentrated or the solution noted. Ie, chlorinated water is fine, but pure chlorine liquid may not be. Consult the chart.

All white Flexible PVC pipe 1/2" to 2" we sell meets applicable UPC, USPC, ANSI, IAMPO, and NSF 50 (white only) specifications, as well as City of LA, Southern Building Code, and Dade County for PVC Hose, but is not for use with potable water. The gray flexible PVC is approved for UL in sizes 1/2", 3/4" 1" & 2" for electrical conduit, but you have to specify "UL rated" in the "comments" section on your order and there is a 10% addition to the price of the pipe. Only gray is available with a UL rating. There are no ratings for black flexible PVC pipe so there are none to meet. Beige flexible pvc pipe has been discontinued.

*Note regarding flexible PVC pipe 2.5" or above, and gray or black colored flexible PVC: There are no plumbing or swimming pool codes for flexible pvc pipe 2.5" and above so these sizes of flexible pvc pipe can't meet any. The color for 2.5" and above is black or gray. Flexible PVC pipe in 2.5" and larger sizes only available by the roll or 4' sections, 8' sections, by the foot and sometimes in the clearance section. Black flexible PVC pipe is only approved for irrigation and pools. Also see shipping cost for additional shipping information. The beige color has been discontinued.
