1. What size pump do I need? |
|
|
This question is not simple to answer, the best
information is our recommended flow in gallons per minute (GPM), from that the
contractor will calculate pump size. Remember that our GPM recommended is the
flow rate needed at the waterfall; the individuals plumbing calculations must be
applied. All Waterfalls and Spill Edge products require a minimum of 10 GPM per
foot of weir opening for a sheet up to 3 feet above the water. Above 3 feet use
the 2000 series or 3000 series with a ¼ inch opening and increase the flow
25-30 GPM for up to a 4 ½' drop. |

2. How do I figure the radius? |
|
|
For one reason or another if the builder does not
know the radius for a concave or convex waterfall, they should either make a
cardboard template of the space where the waterfall is to go (make sure they
mark left and right and up and down and water and wall) OR, they should place a
straight edge from point to point on the front of the waterfall opening and
measure the difference at the center. This information can be used to calculate
the radius. |

3. Why Stainless Steel? |
|
|
Our metal design differs from our plastic in three major
ways. First the metal design has a "no drip lip", which inhibits water
running down the facing and so prevents scale deposits. Second the "free
flow" baffle and water compression design of the metal waterfalls provides
a smoother clearer sheet than plastic. Third the metal units are a beautiful
addition to the environment even when they are not running. The stainless steel
tends to be reflective in it's environment, so it virtually disappears, while
the copper or brass become decorative accents. |

4. Why ABS Plastic? |
|
|
Resiliency. Some plastics (like PVC) get brittle from
sunlight. ABS holds up in sunlight much better than PVC. Our units are
constructed of virgin ABS plastic, the white is a standard color and has UV
protectants for discoloration. The gray and tan colors are custom colors made
exclusively for Custom Cascades and also have color protection to avoid
discoloration over time. |

5. Why Custom Cascades over Other Sheeting Waterfalls? |
|
|
We are the originators of
the sheeting waterfall. We make the best waterfalls and back them up with the
best service in the industry, period. Only Custom Cascade offers colored ABS
plastic, so the units blend into the pools design. Our baffling system allows
for small debris to pass through the unit. Other brands are designed to trap
this small debris, which may lead to internal clogging. We offer more products
and variation than any other manufacture. |
