The statement is false because elongated sleeves are not a standard practice for all cases where plumbing pipes penetrate waffle slab stems. Generally, plumbing penetrations in waffle slabs are typically addressed using standard sleeves or other approved methods that ensure proper sealing and support while allowing for movement and thermal expansion of the plumbing systems. These methods are designed to maintain the structural integrity of the slab and prevent water leakage or damage.

In some circumstances, specific measures may be taken based on project requirements or engineering specifications, but the use of elongated sleeves is not a ubiquitous requirement. Thus, the answer accurately reflects common practices in the installation of plumbing systems in relation to waffle slabs.
