Tanks and Valves

Most tanks in today’s market are made of a fibreglass composite – no surprise here. But what tank size is appropriate? The idea of “bigger is better” cannot be applied as a general rule – quite often rather to the contrary: in many cases, depending on available water production and delivery rates from the respective source, going smaller and decreasing the bed-surface area of any given tank scenario might turn out to be the better way to reach a specific goal.

And there are other parameters that need to be looked at: What are the overall raw water conditions and which removal capacity needs to be accounted for? How many people live in the house, what is the average daily demand and which purpose is the water intended to be used for? Does the in-house flow-rate allow for sufficient back-washing capacities of installed systems? Questions like these and many others on our list, are key questions, which have to be addressed first.

The choice of valves is not an easy one either. For most conditioning units a so called metered valve makes a lot of sense. In other cases, for example when certain media require a regular backwash, regardless of water use, a so called time clock valve may be considered sufficient and the pricier metered valve might turn out to be not necessary. But thoughts like a fluctuating number of visitors, potential gatherings for entertaining, how many loads of laundry are done per week and more questions require good answers for the right decision.

Yet another consideration is the technical set-up of any valve. Which type is the right one for any given water conditions? Vertical piston valve? Horizontal piston valve? Camshaft valve? Turbine driven valve? Non-electric valve? – they all do have their places in our industry and we can make recommendations with the underlying explanations as to which valve type can deal best with the given circumstances.

On top, the idea of servicing valves should not be neglected. Which valve allows for faster service and maintenance procedures and as a result saves costs on service calls? A higher initial purchase price might balance out pretty quickly that way.
