Abstract
A water tester 10 comprises a magnet 12 and a plastics cover member 14, inhere the cover member comprises a handle portion 16 and a testing portion 18. The testing portion includes an aperture for receiving the magnet, and a plug member 24 for sealing the aperture. The testing portion may comprise a thin-walled cylindrical tubular member 22 extending from an end of the handle portion. Preferably, the magnet is also correspondingly cylindrical for insertion into the open end of the tubular member. The magnet may be sealed in place by bonding the plug member into the end aperture of the tubular member with adhesive. The handle portion may be provided with a through hole 20 enabling the tester to be carried on a key ring. In use, the testing portion of the tester, containing the magnet, may be placed in the flow (30, fig.2) from a hosepipe (28, fig.2) connected to the drain valve of a central heating system, to check for the build-up of magnetite (32, fig.2) on the tester, which acts as a visual indication of corrosion in the system water.
Description
Title: Water Tester The present invention relates to a water tester and particularly to a water tester for use in testing central heating system water for the effects of corrosion in the system.
Background to the Invention
A conventional wet heating system comprises a series of radiators to which hot water is supplied through pipes from a suitable source, for example a gas, oil or electrically powered boiler or heater. Over time, the oxygen contained within the water causes corrosion of the inner surfaces of the pipes, radiators or the like. Such corrosion results in the water carrying with it ferrous particles sometimes referred to as magnetite. The magnetite tends to build up over time causing a number of problems.
For example the magnetite may form a restriction to fluid flow resulting in poor circulation causing cold spots. Further, the heating system will typically become of reduced efficiency and may also operate noisily.
It is possible to try and prevent the build up of magnetite within a system by inserting a magnetic filter, of the type described in granted British Patent GB 2402894.
However, at present there is no simple means of testing system water for magnetite and for clearly demonstrating its presence to a lay person, in order to seek their instruction to drain the system, fit a filter and introduce new system water including corrosion inhibitor.
It is an object of the invention to provide a water tester which reduces or substantially obviates the above mentioned problems.
Statement of Invention
According to the present invention there is provided a water tester comprising a magnet and a plastics cover member, the cover member having a handle portion and a testing portion, the testing portion having an aperture therein for receiving the magnet and a plug member for sealing the aperture.
The invention is advantageous because the portion of the tester enclosing the magnet can be placed in a stream of system water, for example, flowing from a hosepipe, and the magnet attracts any magnetite carried by the flow of water and holds it to the tester, the magnetite building up and identifying the presence of magnetite. The rate at which the magnetite builds also indicates the amount of magnetite contained within the system water.
The magnet may be substantially cylindrical and the aperture may be correspondingly cylindrical.
The plug member may be bonded into the end of the cylindrical aperture with adhesive. This ensures that the magnet is held in a water-tight compartment and prevents degradation of the magnet.
The handle portion may be substantially around 50mm in length, 14mm wide and 3mm in thickness. The handle portion may be larger or smaller, but this is the optimum size for enabling the tester to be held comfortably and carried in a pocket.
The handle portion may be provided with a through aperture adjacent a distal end.
This enables the tester to be carried on a key ring.
The edges of the handle portion are substantially rounded, thus preventing the tester from snagging on material, when carried in a pocket.
The water tester may be substantially around 80mm in length.
The magnet may be approximately 3mm in diameter and approximately 20 to 24 nun in length. This size of magnet is sufficient to attract magnetite from a flow of system water.
At least one symbol or trade name may be inoulded or integrally formed on the handle portion. This enables the branding of a company to he permanently carried on the tester for advertising puiposes.
Description of the Drawings
For a better understanding of the present invention, and to show more clearly how it may be carried into effect, reference will now be made, by way of example, to the accompanying drawings, in which: Figure 1 shows a schematic side view, partly in cross section, of a water tester; and Figure 2 shows a schematic perspective view of the water tester of Figure 1 in use.
Description of Preferred Embodiments
Referring firstly to Figure 1, a water tester is indicated generally at 10. The water tester 10 includes a substantially cylindrical magnet 12 contained within a plastics cover member 14. The cover member 14 has a handle portion 16 for holding the tester in use, and a testing portion 18, where the magnet 12 is located.
The handle portion 16 is formed as a substantially flat plastics tab with rounded ends and sides. A circular aperture 20 is provided though the handle portion 16 enabling the handle portion to be retained, for example, on a key ring. The aperture need not he circular, but may be any desired shape enabling connection to a key ring.
The testing portion 18 includes a substantially cylindrical tubular member 22 extending from an end of the handle portion 16. In the construction of the testing device, the cylindrical magnet 12 is pushed into the open end of the tubular member 22 and is sealed therein by a plastics plug 24, which is bonded into the end of the tubular member 22 with adhesive. The wall of the cylindrical tubular member 22 is thin, for example, less than around 0.5 to 1mm in thickness, so that the effect of the magnet is not too significantly reduced.
The handle portion 16 and tubular member 22 are preferably integrally formed in plastics and indicia 26, for example, a company name or logo, is formed in the surface of the handle portion 16. The tester 10 is approximately 80mm in length, the handle portion being approximately 50mm in length and the tubular member 22 approximately 30mm in length. The magnet 12 is approximately 20 to 24 mm in length and approximately 3mm in diameter. Alternative magnet sizes are possible, the size being dependent on the capability of the magnet to attract magnetite onto the testing portion 18 from a flow of contaminated system water. A collar 34 of thicker material is provided between the handle portion 16 and the testing portion 18. This is provided to strengthen the joint between the handle portion 16 and the testing portion 18. This strengthening is necessary to reduce the risk of breakage in use and when the tester is removed from, for example, blister packaging. Products can be subjected to significant bending, when being removed from blister packaging.
Referring to Figure 2, the tester 10 is shown in use. A hosepipe 28 is connected to a drain valve of a central heating system and system water 30 is allowed to flow from the central heating system through the hosepipe 28 and is directed over the testing portion 18 of the tester 10. Magnetite 32 contained in the water flow 30 is attracted to the magnet 12 and is separated from the flow and sticks to the outer surface of the tester 10. As the flow continues, the amount of magnetite 32 on the tester builds up.
The rate at which this build up occurs is an indication of the amount of contamination in the system water, and detection of even small amounts of magnetite 30 gives an indication that internal corrosion of the system is occurring and remedial action is required. When the test is complete, any magnetite build up 32 on the tester can simply be removed using a damp cloth.
The tester 10 enables a plumber to clearly demonstrate to a client that there is corrosion present in a central heating system by virtue of the magnetite carried in the system water. The visual result of the test is undisputable and the test is quick and simple to make. The tester 10 is small and easy to handle and clean. Furthermore, the magnet 12 is not directly exposed to system water.
