Re: Solenoid Valve for water drainage

Another consideration is the standpipe in the toilet tank drains into the
toilet itself which has a builtin p-trap to keep sewer gas out. A standpipe
in an aquarium needs to be drained into a p-trap which has a low probability
of plugging up, else if it fails you still overflow the aquarium. I think if
it were possible it would be better just to have the drain go onto a shrub
bed or something similar than plumbing into the sewer system.

interesting problem...

FWIW, there is probably a drain pipe in your toilet tank that sits
higher than the typical water level (controlled by the float).  If the
float or valve fail, the excess water drains down this pipe, hence your
toilet tank has never overflowed.  Neither has mine, but my toilet
"runs" right now (I love apartment living) because the valve in the tank
is failing.  It's a common problem.
