If the supply line is leaking at the nut, the fitting is usually either under tightened with the gasket not seated, or over tightened to the point that the gasket is damaged. The first thing to check is the gasket inside the nut. Feed line connections on an Ella faucet are made hand tight plus a quarter to half turn with the gasket seated, and going further crushes the gasket and starts a drip that no extra torque will stop. Ella 2 piece and 5 piece fast fill faucet sets ship with two 3/4 inch by 5 foot braided stainless steel supply lines, shut off valves are supplied by your plumber, and replacement braided lines are stock parts.
Likely Causes
- The gasket inside the nut is missing, folded or out of its seat.
- The nut was over tightened with a wrench and the gasket is crushed.
- The braided line itself is damaged, for example a drywall screw through the jacket or a kink at the 90 degree connector.
- The 3/4 inch shutoff valve is the wrong thread type or has a damaged washer, so it never tightens down.
What to Check, in Order
- Close the shut off valves and dry every fitting. Open the valves and watch each connection with the faucet off, then the spout on, then the hand shower on, since some fittings only see pressure in certain positions.
- At the leaking nut, back it off, pull the gasket and inspect it. Reseat a good gasket flat in the nut and retighten hand tight plus a quarter to half turn. Replace a crushed or torn gasket rather than tightening harder.
- Inspect the braided jacket along its full loop. A pinhole, a screw through the line or a sharp kink means the line is replaced, not repaired. Sizes and valve guidance are in water supply lines and shut off valves.
- Check the shutoff valve. The Ella lines end in 3/4 inch female pipe thread, so the valve must present 3/4 inch male pipe thread. A hose thread valve will not seal properly, and a valve that will not tighten is a plumber replacement.
- If the drip is at a faucet piece rather than the line, follow water under the tub, finding the source to separate it from the unions and the hand shower receptacle.
- Order new lines if any jacket is damaged. What a parts ticket needs is in how to order replacement parts.
The video shows the same feed line technique that applies to supply connections on the faucet: check the gasket, thread the connection on hand tight, add a quarter to half turn with a wrench, and never over torque a fitting.
When to Open a Ticket
If a line is damaged or a gasket needs replacing, open a ticket at ellasbubbles.com/support with a photo of the leaking connection, a photo of the whole line from the valve to the faucet, your serial number, and whether you have the 2 piece or 5 piece faucet. Your Ella dealer or the team at (800) 480-6850 sends the matching braided lines and gaskets.
