22 66 00 Chemical-Waste S ystems f or Laboratory a nd Healthcare Facilities- For acid waste and vent systems handling waste discharges at or below 105 degrees F, install either polyvinylidene
fluoride (Kynar, Hylar or equal) or polypropylene piping. For acid waste and vent systems handling waste
discharges above 105 degrees F, install glass borosilicate piping with stainless steel clamps. - No PVC waste or vent systems shall be installed without the Owner’s permission.
22 67 00 Processed Water Systems for Laboratory and Healthcare Facilities- All purification systems shall, in general, be by Liquitech unless the Owner authorizes otherwise. In Colloton
Pavilion, an existing chlorine dioxide system is in place; no Liquitech system shall be added to that distribution
grid until or unless the chlorine dioxide system is removed. - Review the specifics of the proposed installation for each of the following other types of domestic water systems:
