When I finished fixing the new pipes, I built a fountain---or leaky pipe contraption.
The pieces of pipe are connected by PVC elbows and T connectors. To connect all the parts, I used PVC primer and PVC cement.
There are two important notes about this apparatus. First, there are several sections and a cross piece, all to make the structure more sturdy. Second, pipes leading down form the base and are plugged so water does not flow down into those pipes. The idea is to have water flow only in the top level of pipes so there is enough pressure for the water to squirt out.
To produce the leak in the pipes, I drilled 1/8 inch holes in the top pipes.
The funnels, which vary in size, are set over the four ends of the pipes where water enters the fountain.
They are duct taped to the apparatus. I also put in water-proof silicone in the funnel to make a tighter seal and fill in space so water does not leak out the bottom of the funnel.
To secure the fountain to the table, I used duct tape. Note this is done before adding water so the duct tape will stick.
