What's a good test of a pool drain (whether it's working or not)?
My pool is a bit complex, and, I'm trying to troubleshoot a poorly
functioning (supposedly) self-cleaning system, and, one datapoint
would be which of the 5 drains are working at any particular time.
I put my hands next to them, but I can't feel anything flowing.
What's a good test?
Here, for the record, is a picture of the main drain (yellow) on
the deep end and the main safety drain nearby on the wall (red):
Here is a picture of a drain on the wall under one of the skimmers:
And, here are two drains on the bottom of the spa:
Given there are five drains, and three pumps (filter, cleaner, and
spa), it behooves me to figure out which drains are actually working
Hence the question:
Q: How best can we tell whether a drain is working properly at any
one point in time?
Yup. I've been told to use the Phenol reagent (the red stuff) but I
think food color is probably a better idea.
Food coloring is supposed to be non-toxic, but maybe they just haven't trie
d on enough people yet to be sure, or maybe they didn't give the test subje
cts enough. Everything is toxic if used to excess. But food coloring seem
s to me to be the safest, easiest, and cheapest way to go.
On a sunny day, gently enter the pool without stirring the water too
much. If the circulation is adequate the temperature will be the same
from the top to the bottom. For comparison try the same test when the
pump has not been running that day. Water near the top will naturally
be warmer than the bottom.

Thanks to your ideas, I ran a few experiments with the suggested
food coloring near the 5 drains, 2 skimmers, 15 popups, & 6 jets.
I found out what each of the 5 foot-wide drains do (3 floor and 2 wall
drains) plus the two skimmers and the debris basket:
1. Floor drain (main drain, in the deep end)
2. Safety drain (on the deep-end wall near the floor drain)
3. Spa drain (main, one of two drains on the floor of the spa)
4. Spa safety (next to the floor drain of the spa)
5. Skimmer drain (on the wall just below skimmer 1)
Basically, the pool operates on two wholly separate circuits.
From main floor drain and secondary wall drain, to debris canister to
filter pump to filter and back through four wall jets in the main pool and
two wall jets in the spa and two always-on floor rotating pop-up squirters
in the pool.
From skimmer 1 and skimmer 1 wall drain and skimmer 2 to skimmer (aka
cleaner) pump to water valve 1 to water valve 2 to 15 rotating popup
squirters, timed in series by the 9-port water valves.
I'm not sure which of the two floor drains in the spa is the main as
they both suck water when the main filter pump is running. I assume
they're 50:50 as there isn't any way to tell the difference other
than they look slightly different.
