You may require a standard size and shape of cylinder
but need the tappings or bosses relocated to match as close as possible into existing pipe
positions. This is a common requirement and often has no effect on the price
or lead time.
Example: If you wish to run power showers, It is possible to incorporate
dedicated shower take offs on a cylinder.
Should you need to order such
adaptations it is important we all speak the same language when describing
position and dimension. For this reason we use a system as illustrated below.
Please note: Whilst every effort is made to
position tappings and bosses to the required positions it cannot be guaranteed
that minor adjustment of existing pipework will not be necessary. It is for
this reason important your measurements are accurate.

This can be faxed, posted or emailed to us and should
look roughly as follows:
a cylinder you should draw a side-on view marking the positions of each
tapping and boss required, together with the floor to centre measurement (if
this is important).
combination cylinder should be shown like this. Once again marking the
position and dimension from floor to centre of any tappings or bosses if
|You should also
provide a top view of the cylinder or combination tank. Think of it as a
clock face. Mark the position of
each tapping or boss where 12 o'clock is the back, 6
o'clock is the front
So a typical sketch might look

|Your order will pass through
several processes once received so it is important that everything you
require is clear to all concerned (instructions can be mis-interpreted,
embellished or mis-understood if passed on by word of mouth). So make sure
the details of your requirement are clear and easy to understand.
Your drawing need not be a work of art, just
Indicate on your sketch what
each marking represents together with it's position and height from floor to centre
(if this is important). If you do not specify a 'height from floor' for any
element the cylinder will be manufactured to a 'standard' pattern (often a
