What in the World is a WEIR? (Building Our Waterfall Part 4)

The waterfall and stream actually begins 
at the waterfall WEIR. 

There's a WEIR under there

A weir is just a box which diffuses the water 

to create a natural appearing waterfall.

Weirs can be expensive 

and since we're always on the lookout to save money, 

we discovered a much less expensive alternative 

that has worked very well.

Our local hardware store sells a plastic storage bin 
that looks very much like a weir, 
needing only a round hole cut in the side 
to which a PVC plumbing fitting can be attached.

This video provides a complete description of  
how to construct the do-it-yourself weir 
for under $20. 
I deviated slightly from his instructions by purchasing a bulkhead fitting 
that connected through the hole—much simpler. 
Purchase the size that accommodates the size of your tubing.

With the bulkhead fitting in place, 
I inserted the tubing fitting—
first wrapping the threads with Teflon tape.

Here is the completed weir.
The plastic shown here was only for testing, 
to give us a general idea of how this was all going to workout.

In our next post we'll discuss the underlay and liner and attach the liner to the weir. 

Many thanks to my Honeyman who wrote most of this post 
and who always figures out all the hard stuff in my life. ♥
