Definitions

  • the present invention relates to liquid supply systems for use, for example, in supplying water to a building.
  • water is supplied under pressure to a header tank located in a position above the highest point of distribution of liquid in the building and the liquid, usually water, flows by gravity from the header tank to the taps of the system where the water is drawn off as it is required.
  • a header tank located in a position above the highest point of distribution of liquid in the building and the liquid, usually water, flows by gravity from the header tank to the taps of the system where the water is drawn off as it is required.
  • Such systems require pressure sufficient for supplying water to the header tanks in all buildings in a location supplied by a water authority.
  • the pressure supply in the mains to the header tank is in excess of the minimum pressure required to ensure the water supply is adequate for the building.
  • the pipes for supplying the water may vary in diameter depending upon the location of the pipes relative to the water supply source. Such a system is acceptable providing there is sufficient space in the building to accommodate a header tank.
  • the space occupied by a header tank for each individual dwelling is quite large in proportion to the overall space requirements of the dwelling itself, and in consequence, it is desirable to eliminate the use of the individual storage tanks as much as possible.
  • a common header tank in a multi-occupants dwelling means that dwellings in the upper stories usually have too low a pressure and those on the lower floors tend to have too high pressure and the use of water by dwellings in the lower part of the block will tend to detract still further from the useful pressure obtained at the outlets in the upper dwellings of the block.
  • a liquid supply system for multi-occupied buildings having a plurality of distribution levels thereincomprising a plurality of riser mains extending from a service main to a multiple outlet distributor disposed in each dwelling, each riser main being formed from a crosslinked polyolefinic material, means for regulating the liquid flow either to the distributor from the riser main or from each outlet of the riser main thereby providing a substantially constant flow rate and pressure in each of said outlets.
  • a separate riser main may be employed for each storey.
  • a double riser main may be employed for the first few storeys and a single riser extending from the upper end of said multiple riser main to supply the rest.
  • a plurality of distributors may be supplied on each floor, each distributor serving the consumer units of one dwelling.
  • a single distributor may be connected to a WC, bath, hand wash basin, shower, kitchen sink and kitchen appliances such as a dishwasher and a washing machine.
  • the dimensions of the conduits selected to constitute the riser main and the distributor outlet conduits may be selected from three standardised sizes which may be combined to give the necessary flow rate at the distributors based on the pressure existing in the surface main.
  • the conduits of the riser main and the distributor outlets may all be formed from cross-linked polyethylenic material for both the hot and cold water supply in each dwelling.
  • the distributor units may be located in a spaced vertical plane and the feeder pipes may each be disposed below the plane containing the associated distributor unit.
  • the rising main conduits in flats are protected by sheet steel from the connection to the service main to the distributors for the individual dwellings.
  • the protecting steel sheet is preferably spirally round sheet tubing available under the Trade Name “Lindabvent” (uninsulated) or “Lindabsol” (insulated).
  • the conduits themselves are preferably cross-linked polyethylene.
  • connection lines from the distributor to the consumer unit such as a tap, WC, shower or the like may be run in conduits situated in the floor structure or the walls, the conduit lines eliminating from built-in or surface mounted distributor past to different consumer units.
  • This connection line may be installed in a pipe conducting system which employs wall mounted pipe connectors such as described in our co-pending application No. 7916939.
  • the system is connected to a service main 10 which runs adjacent or beneath the building 11 and serves to supply water under pressure from a main water supply, such as a water tower or reservoir via a purification system to a connection point 12 for the building.
  • the connection point 12 may comprise a T-piece junction with a short takeoff pipe 13 terminating in a plurality of pipe junctions 14 each being connected to a rising main pipe 15, there being one rising main pipe for each of the three storeys of the building 11.
  • Each rising main pipe 15 terminates at its upper end in at least one distributor unit 16 for the purpose of interconnection to the service or consumer unit to be connected in the dwelling to which the distributor unit 16 relates.
  • the riser pipe 15 terminates initially at a shut-off cock 17 which is connected upstream of and close to distributor unit 16.
  • the distributor unit 16 is provided with a plurality of distributor outlets 18 each of which have a flow regulator 19 associated therewith to control the flow in feeder pipe 20 to a consumer unit 21, in this case a tap.
  • the flow regulator unit 19 is adjustable to provide a desired flow along each feeder pipe 20 depending upon the flow required at each consumer unit 21.
  • FIG. 5 shows a typical arrangement for a bathroom in which a distributor unit 16 comprises a hot distributor 22 and a cold distributor 23.
  • the hot distributor is provided with a pair of outlets 24 with associated feeder pipes 20 providing a hot supply to the bath/shower 25 and the wash hand basin 26.
  • the cold distributor 23 provides a cold supply via each of feeders 20 connected therewith to the bath/shower unit 25, the wash hand basin 26 and the WC unit 27.
  • the feeder pipes 20 are all formed of a cross-linked polyethylene pipe commercially available under the Trade Name "WIRSBOPEX” and the rising main pipe 15 feeding each distributor from a hot and cold main may also be formed of WIRSBOPEX pipe and provided with a protective shield 28 which is preferably formed from a spirally wound sheet tube commercially available under the Trade Name “Lindabvent” in the uninsulated form or “Lindabsol” in the insulated form. This shield serves to protect the rising main or rising main pipes 15 from the connection 12 to the surface main 10 throughout its rise through the building 11 to each distributor unit 16.
  • the diagram illustrated with respect to Figure 2 provides for a dual connection 12 to service main 10 and provides at least on the lower floors a duplicated rising main 15 comprising two pipes in parallel with H-connector 29 to provide communication between the riser main pipes 15 for equalisation of pressure therein at each of the floor levels from which a supply via distributor 16 is drawn; the supply being drawn via H-connector 29.
  • the riser pipe 15 is formed by a single rising main pipe only having distributor connections 31 connecting with distributor units 16 on each floor in the usual way.
  • FIG. 4 shows a service main 10 with the connection 12 feeding the two rising main pipes 15 which are interconnected at each floor level by means of H-connection 29, the dual riser pipes 15 at the third level 30 of building 11 and continuing thereup by means of distributor connection 31 to distributor units 16 in the manner hereinbefore described with a shut-off cock 17 juxtaposed distributor 16 in the manner described with respect to Figure 3.
  • the flow regulators 19 control the flow of water thereby reducing over consumption at high pressures and ensuring that water supplied to consumer units 21 on an upper floor of a building supply water at a maximum rate corresponding to a maximum flow rate of water issuing from consumer units 19 disposed below, the said upper unit and connected to the same riser main pipe 15.
  • riser main pipes 15 may be of smaller cross-sectional area than riser pipes used hitherto and that all of the feeder pipes 20 may be of the same cross-sectional area.
  • the water supply to a complete flat should be at a rate of 0.8 litres per second.
  • the supply to a bathroom is defined at a maximum of 0.4 litres per second and if a washing machine is installed an additional 0.2 litres per second is required to give a total of 0.6 litres per second. This gives a coincidence value of 0.48 litres per second while a coincidence value for a flat taken as a whole is 0.52 litres per second.
  • the nominal rate for cold water flow is preferably set at 0.8 litres per second for each and in this manner an additional variable is avoided.
  • the supply system in accordance with the invention may be built up from 3 sizes of pipe. Typically 15 by 2.5 mm, 18 by 2.5 mm and 28 by 4 mm. Pipe formed by crosslinked polethylenic pipe manufactured under the registered Trade Mark WIRSBOPEX by the present applicant. Built-in flow regulators are associated with each distributor unit to ensure the correct water flow to each respective discharging consumer unit.
  • Table 2 sets out details of maximum pipe length in metres for various pressure drops, while Table 3 enables the selection of sizes and length of rising main.
  • a distributor unit 16 to a consumer unit 21 select the pressure drop for the feeder pipe 20 and check that the length of line for the selected pressure drop and the nominal rate of flow does not exceed the permissable maximum. Determine the total resistance in the metres water guage of the consumer unit that imposes the highest resistance at the nominal rate of flow and the resistance of any applicable shower or flow regulator, calculate the height in metres between the connection point and the highest position consumer unit and reduce the pressure in B by the sum of the total pressure drops by using the flow regulator 19.
  • the same criteria may be applied.
  • the size and the number of the riser mains may be determined to obtain the appropriate pressure level of distribution at each level.
  • Such a system provides a facile method of computing pipe dimension to be employed and enables pipe size to be standardized on three basic sizes.
