the inside and outside collars to the wall, use a silicone sealer
between pipe and opening to insure a water and air tight seal.

Cementing PVC, ABS OR CPVC Pipe and Fittings
Read and observe all safety information printed on
primer, cleaner, and cement containers.
DANGER
Primer, cleaner, and cements are extremely flammable.
They are harmful or fatal if swallowed. The vapors are
harmful. They may irritate eyes and skin and can be
absorbed through the skin.
PRECAUTIONS
Always store primers, cleaner, and cements in cool, dry,
well ventilated places. Do not store them near heat,
sparks, or flames. Keep containers closed. Use them in
well ventilated areas. Wear impervious clothing while
handling. Do not smoke, eat, or drink while handling.
Wash thoroughly after handling and before eating. Wear
eye protection when handling. If swallowed, drink water,
do not induce vomiting, and call a physician or poison
control center immediately. If inhaled, get fresh air and
seek medical attention if ill feelings persist. In case of eye
and skin contact, immediately flush with plenty of water
for 15 minutes and seek medical attention if irritation
persists. KEEP OUT OF REACH OF CHILDREN.
All primers, cleaners, and cements must meet all local
codes and applicable standards of the American Society
For Testing Materials Standards.
Before using primers, cleaners, and cements, stir or shake,
making sure contents are liquid. Do not use if found to be
lumpy or jelly-like.
1. Cut pipe ends squarely removing all burrs and dirt.
2. Dry fit pipe and fittings to be connected for proper fit.
3. Clean pipe and fitting with a primer/cleaner.
4. Apply a thin coat of cement to fitting, avoiding
puddling inside.
5. Apply a liberal coat of cement to pipe leaving no voids.
6. QUICKLY assemble parts while cement is fluid! If you
wait too long, re-coat pipes.
7. Push pipe completely into socket of fitting, turning as it
goes until it bottoms.
8. Hold pipe and fitting together for 30 seconds. Then
carefully clean off excess with a cloth. Allow connec-
tions a sufficient time to cure before disturbing.
9. Remember that vent pipes must be adequately and
securely supported.
