Custom Fit Connections
E.
If you determine the PEX supply tubing for this faucet is too long and must be
shorter to create an acceptable installation, be sure to read the instructions and
plan ahead. When cutting the supply tubing the installer accepts the responsibility
to do so in a way that allows a leak-free joint to be created. Delta is not responsible
for tubing that is cut too short or cut in a way that will not allow for a leak-free joint.
For custom fit installations, you must use RP50952 sleeves supplied with model and nuts
included on supply lines. Tube cut must be straight. See plastic sleeve installation
instructions found in RP50952 and included in this document for more information.
Secure metal nut (1) on faucet tube to check valve connection (2) and hand tighten, then
tighten an additional 2 turns with wrench. DO NOT OVERTIGHTEN. Repeat for other
tube. WARNING: Do not use pipe dope or other sealants on water line connections.
Potential Problems and Remedies
● Tubing is not cut perpendicular to the axis of the tube: carefully make an additional cut,
being careful not to cut the tube too short.
● Tubing is cut too short: buy a coupling union and a replacement supply line that mate
together from a store. The coupling union end intended to connect to the faucet must mate
to the standard 3/8" connection nuts and plastic sleeves supplied with the faucet.
● The plastic sleeve or connection nut is lost: purchase a replacement nut and/or plastic
sleeve that are designed to seal with PEX tubing. NOTICE: DO NOT use a metal sleeve,
RP51243 gasket (supplied with faucet) or ferrule in the place of the plastic sleeve
supplied, it may not create a leak-free joint.
