10.0 Frequently Asked Questions
Question 1
Can Restrain sewer pipe be used with traditional PVC drain,
waste & vent pipe and fi ttings?
Answer
Yes, Restrain sewer pipe is fully compatible with PVC DWV
pipe and fi ttings, manufactured to AS/NZS1260.
Question 2
How do I test Restrain sewer pipe on site?
Answer
Restrain sewer pipe is tested in the same as traditional
PVC pipe. Refer to Section 9.
Question 3
Can I use solvent cement DWV fi ttings on Restrain sewer
pipe?
Answer
Yes, Restrain sewer pipe has the same outside diameter
as traditional PVC DWV pipe, and can be used with PVC DWV
fi ttings designed for solvent cement jointing. Remove the
threaded Restrain socket or spigot before assembling of
the solvent cement joint.
Question 4
What type of lubricant do I use when jointing Restrain
sewer pipe?
Answer
We recommend CRC808 or Gensil 601 silicone spray
lubricant.
Question 5
Why can’t I use standard rubber ring pipe lubricant on
Restrain ?
Answer
Standard pipe lubricant looses its slippery properties soon
after the joint is made. Silcone lubricant remains slippery
longer, which may allow you to unscrew the threaded joint
should the installation need changes.
Question 6
Why is a different pull head necessary?
Answer
Standard wind-up pull heads designed for PE pipe may
not be suitable for Restrain, as the internal engagement
grooves may not “grip” effectively into the dense PVC
surface. Cross-bolt style pull heads, for internal or external
use, are recommended for Restrain pipe, as shown in
paragraph 7.3.
