in any case, any failure caused by improper installation and/or piping connections may void the
warranty of Pentair products;
•
in the same way, using lubricant* on the valve thread is not allowed and will void the warranty for
the valve and tank. Indeed using lubricant there will cause the valve to be over-torqued, which
may lead to valve thread or tank thread damage even if the connection to piping has been done
following the above procedure.
*Note: Use of petroleum-based grease and mineral based lubricant is totally forbidden, not only on the valve thread, since
plastics used (especially Noryl) will highly suffer from contact with this type of grease, leading into structural damage hence
to potential failures.
