Water feature Mistakes
This is a nice looking soon to be water feature, or is
it?

During the installation of a custom made water feature
similar* to this, two 15mm pipes
were run under the floor area, one for water flow, one for water return. The pump is
to be connected at the other end of these pipes which is around 8 metres
away.
Below is a list of errors that were not thought of with
the installation of this feature.
A nozzle was requested to be fitted to the top outlet.
The height and style of this feature means that a nozzle will only serve
to spread the water further outside the bottom bowl, please see the
jw
rule for more information.
The return pipe diameter is too small, since the pipes
are just under the gravelled area they are level so the only reason the water
will return to the pump is gravity, pumps pump water out they do not suck
it in. The return pipe needs to be much bigger than the flow pipe if this
is ever going to work.
The pump position is above the gravelled area which means
its inlet will be just below water level
The water return pipe is just protruding from the base of the
pool. it has no screen to stop debris from entering the pipe, when debris
does enter the pipe and it gets lodged in the pipe how will you get it
out?
Our solution?
To cut the pipes off, use one as a conduit for a cable.
Mount the pump in the bottom pool of the feature.
For those of you thinking why not use a central heating
pump the answer is two fold.
A central heating system is a closed loop, water can be
pumped very high, and through small diameter pipes because as the water is
pumped away, it forces water into the pump inlet at the same rate, it is
pumped out because it is a closed system.
A central heating pump will also corrode because of the
new oxygen being introduced.
Central heating pumps are called circulators for a
reason. * We have only used this picture as an example,
as it is the same style as the "problem" feature. This feature has a
hollow stand for the pump to sit in. You may also want to
