A valve that closes to prevent backward flow of liquid
(Check valve) used to provide flow through a pipe in one direction only. When installed between an external filter and the pond, it keeps the dirty water in the filter from flowing back into the pond if power is lost. They are also used to keep an external pump primed if power is lost.
(Check valve) A device inserted into a moving liquid stream that allows flow of the stream in only one direction; most often used on the inlet and outlet sides of an HPLC pump.
(Check valve) A check valve, clack valve, non-return valve or one-way valve is a mechanical device, a valve, which normally allows fluid (liquid or gas) to flow through it in only one direction.
(watt) Scottish engineer and inventor whose improvements in the steam engine led to its wide use in industry (1736-1819)
A district in southern Los Angeles in California, home to much of the black population of the city
English poet and theologian (1674-1748)
(watt) a unit of power equal to 1 joule per second; the power dissipated by a current of 1 ampere flowing across a resistance of 1 ohm
How it looks once you dry the floor
The white thing to the left/bottom foreground
is the water heater.
The pvc pipe to the center with
the check valve is the waste water pipe.
Because this part of the house is
"below grade", any waste water
in this part of the house
must be pumped up and out
in order to get to the septic tank outside
which is below ground, but above
the level of the floor in this part of the house.
Water, as the high school chemistry teachers
tell us, "seeks it's own level".
A more accurate phrase for this situation would be
an old Army addage...
"$h*t rolls down hill".
The pvc pipe to the right of the waste water
pipe is merely a vent. It allows noxious vapors
to pass outside, all the way up to the roof where
the wind disperses them.
Just above my toe is the clean out port
which allows access to the waste water pipes
in the house for using a snake to clear blockages.
Mike Watt & Kramer, computing
In February 2008 I did a tour (as drummer) with bassists Mike Watt and Kramer. Here we see my bandmates relaxing with their computers in the luxuriously appointed backstage area at one of the tour venues.
