Step 4 - Dry Fit

Check pipe and fittings for dry fit before cementing. For properinterference fit, fitting should go over end of pipe easily but becometight about 1/3 to 2/3 of the way on.Too tight a fit is not desirable;you must be able to fully bottom the pipe in the socket duringassembly. If the pipe bottoms in the fitting with no interference but not loose, a satisfactory joint can be made providedthe pipe and fitting are not out of round. To see if a fitting is acceptable for bonding, hold a short piece ofthe pipe in a vertical position and insert the fitting on the end. If the fitting falls out of the pipe, do notassemble. All pipe and fittings must conform to ASTM or other recognizedstandards.
