Faucet Supply Hose Leaking Under the Deck: Access, Identification and Replacement

Updated September 2026

If the flexible supply line under your tub deck has split or is dripping where it feeds the spout or the hand shower, you do not need a new faucet. The hose is a replacement part, and Ella faucet parts are covered under the lifetime parts warranty. Send photos of the leak and your serial number through ellasbubbles.com/support, and the matching hose ships to you. You reach the hose by removing the small magnetic access panel on the front of the tub next to the door, and a local licensed plumber does the swap.

Where the Hose Is and How to Reach It

The faucet body sits on the deck, and its supply lines run down behind the front apron to the mixing valve or diverter. A small access panel on the front of the tub next to the door is held on by magnets and pulls straight off by hand. Behind it you will see the lines that connect the valve or diverter to the spout and the hand shower. Room is tight, so a flashlight helps. The serial number label is behind the same panel, so note it while you are there.

Which Hose Do You Have?

Ella has used several faucet sets over the years, and each uses its own supply lines, so the first thing support needs to know is which faucet is on your tub. Your manual may show a metal flex line while the tub itself was fitted with a black flexible line. Both are normal, and the replacement is matched to what is actually installed. To identify the faucet, count the handles on the deck. A set with a temperature handle, a spout handle and a sprayer handle is the thermostatic control valve (TCV) faucet. Two-handle and five-piece sets use different lines. If you are not sure, the faucet identification guide walks through the differences.

Getting the Replacement Hose

  1. Shut off the hot and cold supply valves to the tub, or the house supply if the tub has no stops.
  2. Remove the magnetic panel beside the door and locate the leak. Black or crusty buildup around a fitting usually marks the spot.
  3. Photograph the leak point, both ends of the hose where they connect, and the faucet handles on the deck. Note whether it is the hot or the cold line and whether it feeds the spout or the hand shower.
  4. Open a ticket at ellasbubbles.com/support with your model, serial number and photos.
  5. Once the hose is matched, it ships to you under the parts warranty. The general process is described in how to order replacement parts.

Who Does the Work

Ella ships parts and supports your plumber by phone, but does not send technicians. Swapping a supply hose is a routine job for a licensed plumber. Your original installer is a good first call, since they know the tub, although some installers only service tubs they installed. If you need a referral, see find a licensed installer. If the hose connects to the valve itself, the plumber can also check the valve connections while the panel is off. For a full set swap, see replacing your faucet set or hand mixer.

While the Panel Is Off

A leak under the deck sometimes shows up first as a wet ceiling in the room below, and the hose is not always the only cause. If a ceiling or access opening is already open, have your plumber look over the drain connections and the hydro or air lines at the same time, then run the faucet and each therapy system for a few minutes before closing everything up. That saves opening things up twice.

Common Questions

Is the supply hose under the deck a warranty part?
Yes. Supply lines for an Ella faucet are covered by the lifetime parts warranty, so the hose ships at no charge once the leak is verified from your photos. Labor to install it is not covered, so a local licensed plumber does the swap.
How do I get to the hose without removing the tub?
You can access the supply hose without removing the tub by pulling off the small magnetic access panel located on the front of the tub next to the door. This panel is held by magnets and can be removed by hand. Behind this panel, you will see the supply lines that connect the valve or diverter to the spout and the hand shower, and a flashlight can help in the tight space.
Why does support ask how many handles my faucet has?
Different Ella faucet sets use different supply line hoses, and the handle layout is the quickest way to tell them apart. A temperature handle, a spout handle and a sprayer handle together indicate the thermostatic control valve faucet. Photos of the handles and both hose fittings let support match the right part.
Is this the same hose as the hand shower hose?
No. The hand shower hose is the visible flexible hose that runs from the deck to the sprayer head. The supply hose under the deck carries water from the valve to the spout or the sprayer connection. See replacing a cracked hand shower hose for the visible hose.
Can you still match the hose on an older tub?
Yes, Ella's Bubbles can usually match the correct supply hose for an older tub. To help the support team identify the correct replacement, send photos of the faucet handles on the deck, the leaking hose itself, and both ends of the hose where they connect. This allows the team to match a current equivalent, and information on older faucet sets is available in the guide to Parts and Support for Older or Discontinued Ella Tubs.
