When you get ready to work with the PVC be sure to sand the areas of the plastic that will be glued ( inside the couplings and elbows especially ), clean them off , apply your glue , put them together quick , and let the joint set imoble for about 10 min. If you get that glue on you ( it smells like hell ) use fingernail polish remover to take it off ( real cheap hairspray for you clothes ) . Flush the new piping real well out with water after it's all dry .Once the glue if dry you souldn't be able to taste or smell it .
