5.4 - Water pump
a - Install the water pump below the water level
and above the aspiration level to make the
auto draining system work (picture 11).
Installing the water pump below the
aspiration level makes the water stay in the
pipes, causing bad smell, fungal and
bacterial appearance (picture 12).
b - Never let the aspiration pipes go above the
jet pipes (picture 13). This causes siphoning
(the water doesn’t reach the water pump,
damaging the mechanic seal and causing
leaks).
c - Connect the water pump according to the
instructions of the “coupling kit” found
inside the water pump box. If you purchase
a water pump from another manufacturer,
read the manual that comes with the
product.
d - Position of the water pump: it is defined
when the product leaves the factory but it
can be changed according to the client’s
needs. However, it must be installed in a
way that the maintenance is easy. The
installation of the water pump far from the
bathtub is not recommended, as the longer
the distance the lower the water pressure.
Should you make any change, move it 2m at
the most.
Note: Any change must be made by a
specialized plumber.
