the pump appears to be the problem and you need help with your
investigations, please use the Contact Page to book an appointment for a
PSP engineer to visit. To obtain more information on the

Owners Club, please visit the Members Page. The information on this page
will be added to the appropriate section for
members future searches.
Water is pushed through a bed of filter sand and removed through a set
of lateral tubes at the bottom.
Sand dunes are not only made of sand
but also of water. You don't have to dig very far to
see the moisture
in the sand. One of the unique features of sand is that it helps filter
water that passes through it. Go out
to the sand and have the students
dig into the sand and describe what they find. Talk about why they think
it is cool and wet.
Ask the students where they think the water came
from and where they think it goes. Doing Castles in the Sand prior to
this
activity helps students understand how sand and water work together
through a process called capillary action.
