Rotating ball water feature
Rotating ball feature, how it works
You have seen a rotating granite ball here is a way
for you to install a small rotating ball feature
 |
First a standard water tank is installed to act as a sump,
pump, pipe and grille added. Water was added at this stage to
give the tank more weight. |
 |
The ball base is then added along with supports (they are
under the base) Silicone sealant is then added to fill the small
gap between pipe and inlet orifice. |
 |
Ball and decorative material added then switched on, sit back
and enjoy |
 |
Drawing of how it is done, note the pump is off set to allow
for easy pump servicing. This set up applies to any size of ball |
|
|
This ball is
hand made, and solid granite, the £1,000 price tag soon put people off.
(Any one want to guess how much a 1m diameter ball used to cost?)
The bigger balls are installed in a similar way, except the sump is
obviously not a plastic water storage tank. They are rotated by the
water pressure and its direction, the water actually lifts the ball in
its socket which is how come you can push them by hand. If the socket is
deep (depending on manufacturer) then these will require a bigger pump.
