Troubleshooting

1. Prior to installation of sanitary fittings, it is imperative that the plumbing pipes be cleared out for construction material that might be clogged in them. To enable this one can allow the water to openly flow, by opening the gate valve near the Storage tanks for a short period. Once dispensed of clogging material, one can go in for installation of Ark CP Fittings.

2. One should also ensure that the Outlet of the storage tank is at least 2” above the bottom level, so that any sediment if mixed in the water supply, settle down at the bottom of the storage tank and do not carry on through the plumbing pipes with the water flow.

3. Plumbers should not use more than 8-10kgf to tighten bib shanks, angle shanks and wall mixer legs to the plumbing pipes. Though the faucet body is metallic, one cannot expect the body to take any amount of force.

4. Installation diagrams/ leaflets are given with complex fittings to make it relatively easy for the plumber to install the faucets; the plumber should refer to the diagrams before going in for such installations.

5. 90% of all breakdowns of a typical sanitary fitting occur in its spindle assembly. This is because the spindles experience the most wear and tear. Some part of a spindle assembly is always in contact with water. And because water contains salts, especially hard water, over a period of time this salt deposits over the moving parts of a spindle assembly, leading to its deterioration. Removal of the salt deposits through thorough washing and preferably by applying good quality silicon grease can sustain the spindles for longer periods of time.

6. It might be a good idea to install a filter near the tank outlet to prevent coarse/ rough deposits present in water to find their way to the spindle assembly. This shall increase the life of the spindles.

7. Nowadays most sanitary fittings use Foam Flow aerators or jallis. These aerators have a dual purpose; not only do they save water, typically up to 50%, but also make the flow more laminar and smooth. The problem these aerators generally face is the presence of impurities in the water. These impurities typically cannot pass through the mesh area of the aerator and over a period of time, they can choke off the water supply. Typically all faucets provide a cut in the Pearl-mix outer or the mouth of the faucet to enable easy opening of the mouth and the aerator. Cleaning the aerator is very easy as the impurities can be ‘brushed away’ or drop off on their own when exposed to free water.

8. CP faucets are plated using a Nickel base over polished brass and then a Chrome layer over the Nickel base. Chrome is a very hard metal and has both decorative as well as protective value. Generally a thin layer of Chrome (0.3µ) over a 10µ layer of Nickel is enough to keep the faucet shining over its lifetime. By cleaning the faucet once in 10-15 days, using a dry clean cloth, to remove the salt deposits from is all what is needed to make the fitting finish last for very many years. (Under good maintenance fittings have been reported to last even up to 30-40 years, with the lustre intact).

9. One should never use chemicals like Harpic, detergents or any other washing or cleaning powder over the tap, as the acid present in these chemicals weaken the bonds between Chrome, Nickel and brass which can ultimately lead to their erosion.

10. One should also avoid contact of sharp objects on the surface of the tap, especially if one has gone for a powder coated or colour finished tap. The chemical (adhesive) bonding between the colour pigment and the brass surface is typically not as strong as the electrical bonding between Chrome/ Nickel and the brass surface.

11. Typically CP fittings should be installed when all masonry and paint/ polish job is over in the bath/ kitchen/ wash area. If one has installed the faucets before the masonry work is finished, then it is imperative that the faucets be covered suitably with plastic bags or if possible, be removed altogether. The cement mix, paint, varnish oil is harmful for the surface finish of the tap as these impurities weaken the underlying bonds between Chrome, Nickel and Brass and can lead to their erosion or can cause unwanted permanent deposition on the surfaces.

12. Showers have small apertures which enable water deliverance in sprinkle/ spray form. Sometimes due to the presence of salt deposits in the water these small apertures can get clogged, especially if the device has not been in use for a period of time. If the showers have rubberised apertures as in the case of European Bossini showers, then the cleaning is very easy and can be done by just rubbing the apertures with or fingers for a few minutes while the shower is left on. Slowly all clogged impurities shall get washed away through the combined effect of the force of the flow and the pressure of our fingers. In case of normal aperture showers, one can dismantle the shower by opening the thread and can scrub off the deposits from the ‘jalli’ of the shower by using a brush. The cleaned jalli of the shower can be assembled back and the shower will then function like new. Similar maintenance works for Hand showers and body jets.

13. Health Faucet showers are a little more delicate than ordinary hand or Overhead showers. Their lever mechanism is a little fragile as it is not metallic but made of plastic and rubber parts. Hence it is essential that the health faucets be not exposed to pressures higher than 1.5-2 bars (kg), otherwise over a period of time, the lever side might leak or even break down. In case of higher pressures, pressure reducing washer (or a gate valve to restrict the water flow) is recommended.

14. Flexible Hoses are made of rubber hoses over which metal coils are wrapped with brass nozzles at ends. It is important that during use the coils are not twisted too much. In case of too much twisting, the coils can come off. It is also important that the pressure to which the flexible pipes are exposed should be kept below 1.5 to 2 bars (kg). A greater pressure can lead to bursting of these pipes as they are not of metal. In case pressure in the plumbing pipes is higher, one should use Pressure reducing washer to decrease the dynamic pressure to which these pipes are exposed (or a gate valve to restrict the water flow).

15. Push Cocks should not be exposed to pressures greater than 1 bar. These devices are meant to function only in one storey house or at public conveniences where there is no pressure boosting. If pressure is boosted beyond 1.0 to 1.5 bars (kg), the operation of the push cock button becomes hard. In case of higher pressures, pressure reducing washer (or a gate valve to restrict the water flow) is recommended.

16. Flush Cocks should not be exposed to pressures greater than 2 bars. These devices are meant to function only in one storey house or at public conveniences where there is no pressure boosting. If pressure is boosted beyond 2.0 bars (kg), the operation of the flush cock button becomes hard.

17. Ark Lab Taps are available in two distinct identities – as a Supreme variant for the traditional look and as an Opera variant in its trendy avatar. The levers in Lab Taps are excessively long to enable elbow enabled opening (for hygiene, zero germ transference). Due to this elongation and force applied at the edge of the lever is increased manifold at the fixed end (on the spindle punch). Thus one needs to be careful about the force to be applied here.

18. Ark Bath accessories are made of Brass sheets and pipes. Unlike sanitary faucets, the accessories are not much exposed to water. However since they are usually fitted in areas, where there is a rich content of moisture in the air, as well as frequent splashing of water droplets, they do need to be cleaned regularly to maintain the lustre/ polish of the CP Finish. The procedure for cleaning is very simple as explained earlier and basically involves just the removal of salt deposits of water (present in water supply). A bit more care might be required for the soap dish as the chemical of the wet soap might react with the CP finish and thereby lead to dulling of the polish/ lustre. A regular cleaning of the soap dish after bath/ wash activities are over (for example before retiring for the night or after the morning chores are done) will avoid this reaction and keep the soap dish shining as long as the other CP faucets. Detergent cakes should not be kept on the soap dish, as the chemicals in a detergent are far stronger and chemically reactive than the bathing soap. Similarly one should never use detergent powder or cake to clean the tap/ accessories. A gentle rub with a dry cloth, periodically after finishing off the morning/ night rituals is all that is needed to keep the lustre shining for years.

19. Flush Valves don’t have a problem with pressures up to 3-3.5 bar. Higher pressures than this might also make the operation of the flush valve a little harder. The main area of concern in Flush Valves however is of water cleanliness. Coarse particles, like rough sand or small pebbles or brick particulates can choke off the slit that enables the hydraulic automation of the lever in the return stroke of the flush cycle. With a result that there might be continuous flushing without the lever returning back (to close of the valve, a frequent problem where water quality is bad). One may install a filter near the storage tank outlet to keep off the coarse particulates from choking the Flush Valve mechanism.
