  • a tap or a faucet mounts on a surface, e.g. a deck, near a bath tub or a sink.
  • the tap is arranged to deliver fluid into the bath tub or the sink.
  • the tap is adapted to be fitted to one or more fluid supply pipes located at least in part behind the surface.
  • a user can operate the tap to control fluid flow rate and/or temperature into the bath tub or the sink.
  • Such a tap may be termed a deck-mounted tap or a deck-mounted faucet.
  • An isolation valve is typically present in the fluid supply pipe(s) to which the deck-mounted tap is connected.
  • the isolation valve is required to allow fluid flow to be cut off, e.g. during maintenance or replacement of the tap.
  • the isolation valve is typically not easily accessible, since it may be located behind the surface, e.g. beneath the deck. Accessing the isolation valve may involve, for example, removing a bath panel.
  • a first aspect provides a plumbing fitting mountable on a surface, the plumbing fitting comprising:
  • the isolation valve When the plumbing fitting is mounted on the surface, the isolation valve is located in front of the surface meaning that the isolation valve can be readily accessed, e.g. for maintenance, servicing or repair.
  • the isolation valve is operable to allow or prevent fluid flow along the inlet waterway.
  • the isolation valve may be manually operable.
  • the isolation valve may comprise a ball valve.
  • the surface may be a deck, e.g. adjacent a bath tub or a sink.
  • the plumbing fitting may comprise a tap or a faucet.

  • Such a surface may be termed a deck.
  • the deck may extend at least partially around a perimeter of the bath tub or the sink.
  • the mixer tap 1 comprises a mixer valve body 2 in the form of a bar valve.
  • a thermostatic mixer valve (not shown) is disposed within the mixer valve body 2.
  • the thermostatic mixer valve (not shown) comprises a valve chamber having a first valve chamber inlet for receiving a first inlet water flow and a second valve chamber inlet for receiving a second inlet water flow and a valve chamber outlet for an outlet water flow to pass through.

  • a spout 5 protrudes forward from a central portion of the mixer valve body 2 and provides fluid communication from the valve chamber outlet to a spout outlet.
  • the spout outlet may be arranged to emit water into a bath tub or a sink.
  • a first elbow component 6 is adapted at a first end to be connected to a first water supply pipe (not shown). At a second end, the first elbow component 6 is connected to the mixer valve body 2. The second end of the first elbow component 6 may be threadably connected to the mixer valve body 2.
  • the first elbow component 6 provides at least in part a first inlet waterway providing fluid communication from the first water supply pipe to the first valve chamber inlet.
  • the first elbow component 6 has a bend at an intermediate point along its length.
  • a first straight section is disposed upstream of the bend and a second straight section is disposed downstream of the bend.
  • an isolation valve is disposed in the second straight section of the first elbow component 6. The isolation valve is operable to prevent or permit fluid flow along the first inlet waterway.
  • a second elbow component 7 is adapted at a first end to be connected to a second water supply pipe (not shown). At a second end, the second elbow component 7 is connected to the mixer valve body 2. The second end of the second elbow component 7 may be threadably connected to the mixer valve body 2. The second elbow component 7 provides at least in part a second inlet waterway providing fluid communication from the second water supply pipe to the second valve chamber inlet.
  • the second elbow component 7 has a bend at an intermediate point along its length. A first straight section is disposed upstream of the bend and a second straight section is disposed downstream of the bend.
  • an isolation valve is disposed in the second straight section of the second elbow component 7. The isolation valve is operable to prevent or permit fluid flow along the second inlet waterway.
  • the first elbow component 6 and the second elbow component 7 are substantially identical. For conciseness, only the second elbow component 7 will be described in detail. It will be appreciated, however, that the disclosure relating to the second elbow component 7 applies equally to the first elbow component 6.
  • the second elbow component 7 constitutes a tubular member 108 having a first end 104 and a second end 106.
  • a second inlet waterway 120 extends through the tubular member 108 from the first end 104 to the second end 106.
  • the first end 104 is adapted to be connected to a water supply pipe (not shown).
  • the second end 106 has a threaded portion for connecting the second elbow component 7 to the mixer valve body 2.
  • the second elbow component 7 comprises a bend 105.
  • the bend 105 is located between a first straight section 103 located upstream of the bend 105 and a second straight section 107 located downstream of the bend 105.
  • An isolation valve in the form of a ball valve 101 is arranged in the second straight section 107 and is operable to prevent or allow flow along the second inlet waterway 120.
  • the ball valve 101 includes a ball 121 with an aperture 122 therethrough.
  • the ball 121 is sealed within the second inlet waterway 120 by two o-ring seals 124, 126.
  • a spigot 102 extends from the ball 121 through a wall of the second elbow component 7 so that an end of the spigot 102 is accessible by a user.
  • the end of the spigot 102 is provided with a groove 118 for receiving a tip of a screwdriver or the like.
  • the spigot 102 is operably connected to the ball 121 by a spigot tip 136 received in a slot 138 in the ball 121.
  • a screwdriver can be used to turn the spigot 102 and hence rotate the ball 121 within the second inlet waterway 120.
  • the ball 121 can be rotated between an open configuration (shown in Figures 3 and 6 ), which allows fluid flow along the second inlet waterway 120 and a closed configuration (shown in Figures 4 and 7 ), which prevents fluid flow along the second inlet waterway 120.
  • the aperture 122 through the ball 121 is aligned with the second inlet waterway 120. Hence, fluid can flow along the second inlet waterway 120.
  • a pair of o-ring seals 132, 134 are disposed around the spigot to provide a fluid-tight seal within the second elbow component 7.
  • a clip 130 is arranged to hold the spigot in place.
  • the second elbow component 7 is configured to be mounted on a surface such as a deck in any suitable manner. When mounted on the surface, the surface may be disposed between a first flange 112 and a second flange 116. The first flange 112 and the second flange 116 are located towards the first end 104 of the second elbow component 7.
  • FIG 8 shows a plumbing system 800 comprising a tap 801 according to the present disclosure, e.g. the tap 1, arranged to dispense water into a bath tub 802.
  • the tap 801 is mounted on a deck 803 adjacent the bath tub 802.
  • the tap 801 is connected to one or more water supply pipes (not shown).
  • the tap 801 has one or more isolation valves disposed within one or more inlet waterways at a location accessible from in front of, i.e. above, the deck 803.
  • FIG. 9 shows another plumbing system 900.
  • the plumbing system 900 comprises a plumbing fitting 901 comprising a tap, e.g. a mixer tap, and a diverter.
  • the plumbing fitting 901 is arranged to dispense water into a bath tub 902 either via a tap spout 907 or via an overhead shower 904 in fluid communication with the plumbing fitting 901.
  • Fluid communication from the plumbing fitting 901 to the overhead shower 904 is provided by a riser tube 905 and an arm 906.
  • the diverter is operable to allow user selection of the mode of dispensing the water, i.e. via the tap spout 907 or the overhead shower 904.
  • the plumbing fitting 901 is mounted on a deck 903 adjacent the bath tub 902.
  • the plumbing fitting 901 is connected to one or more water supply pipes (not shown).
  • the plumbing fitting 901 has one or more isolation valves disposed within one or more inlet waterways at a location accessible from in front of, i.e. above, the deck 903.
  • the isolation valve is disposed within the plumbing fitting and is therefore easily accessible, since the isolation valve will be in front of the surface, e.g. deck, on to which the plumbing fitting is mounted. Hence, maintenance, servicing and replacement activities may be less disruptive.
  • the plumbing fitting may be mounted on to a deck adjacent a bath tub.
  • any and all servicing, maintenance and/or replacement activity may be performed above the bath tub, without having to remove and/or damage bath panels to access the underside of the bath tab where isolation valves are normally found.
