No. The pipe will expand in warm weather and contract in cold weather. During installation the fabric will typically reach or cover part of the fitting. If the fabric falls short of reaching the fitting, it is not cause for alarm. Installers can very easily pull or push the pipe to make it slightly longer or shorter. If a space remains between the fabric and fitting, the System Sand will bridge over exposed pipe perforations, preventing additional System Sand from entering the pipe and suspended solids from exiting the pipe.
