STEPS TO GLUE PVC PIPE PROPERLY
∂∂ Cut the pipe square
∂∂ Remove the burrs inside and outside of the pipe
∂∂ Clean the PVC Pipe with a rag to remove dirt and moisture
∂∂ Check the dry fit (The pipe must enter at least 1/3 of the way
in without force! If the fit is too tight, file or sand pipe. Don't
make flats or gouges on it.)
∂∂ Remove floss by wiping the pipe and fittings with cleaner or a
primer, or sand them
∂∂ Apply cement
∂∂ Flow cement on with a full brush
∂∂ Brush a thin coat in the fitting
∂∂ Brush pipe again
∂∂ Keep brush in cement between applications
∂∂ Work fast and don't use too much cement!
∂∂ Assemble immediately
∂∂ Rotate and bottom the pipe in the socket, while the pipe is still wet
∂∂ Rotate only 1/4 turn
∂∂ Hold the pipe for about a minute
∂∂ Important: Get help on large sizes or use a mechanic al helper
∂∂ Wipe off excess cement — especially the bead!
∂∂ Let cement dry
∂∂ Wait 30 minutes. If it's 70˚ or hotter, wait 30
minutes; 40˚ to 60˚ — wait 1 hour; 20˚ to 40˚— wait 2 hours
∂∂ Snake pipe in ditch side to side
∂∂ Shade pipe with backfill
∂∂ Use soft dirt without clods or rocks for the first few inches,
leaving joints exposed for inspection
∂∂ Set period
∂∂ Depending on the type of cement, size of pipe, air temperature
and dry joint tights, your pipe will take a certain time to dry
∂∂ 24 hours is considered to be a sage period to be allowed to
stand before testing
THRUST-BLOCKING PVC PIPE
∂∂ Water under pressure exerts thrust forces in piping systems at:
Changes in pipe size or direction, dead ends and valves.
∂∂ The design of thrust-blocking requires knowledge of the thrust
generated and the bearing strength of the soil against which the
thrust block will be placed.
∂∂ To be effective, a thrust block must: 1) be placed against undisturbed or fully compacted earth; 2) contact the fitting over
a sufficiently large area so as not to create stress points on the
fitting; 3) have sufficient area on the soil to restrain the thrust
without exceeding the bearing strength of the soil.
