I got a well pump and old fashioned (non-bladder) tank. The tank is
in a 15' deep pit that used to be a cistern. Every few months the
tank gets waterlogged, and I got to go down in the pit to drain the
tank. The top of the old cistern is barely large enough to get myself
in there, and the ladder has to be nearly straight up and down because
there isnt enough room to put it at an angle. This is one of those
chores that gets real aggravating after awhile.
I have dedided that it's time to do something about this. I looked at
a bladder type tank yesterday. They are costly, but if it solves this
problem, it's worth it. However, I noticed that those tanks only have
one pipe connection on the bottom, so I'd have to replumb the whole
thing. (My present tank has one INPUT pipe, one OUTPUT pipe, and
another 1/4" pipe hole where my pressure switch and guage are
connected. I assume I'd have to use a bunch of pipe fittings to hook
the INPUT, OUTPUT and PRES SWITCH all on the pipe assembly, so the
pipe becomes the connecting point for everything, instead of the tank.
All of this looks like work, but I can do it.
However, I have never understood how to pressurize one of those tanks.
Yes, I know I take my air hose and apply pressure on the little tit on
the top. However, to what pressure? The HIGH pressure, or the LOW
pressure that my pressure switch is set for. For example, I normally
run 35 Low / 55 High for water pressure.
Then, so I just pressurize it before I turn on the water, and use a
tire guage to get the correct pressure?
I could use a little advice on this!!!!
Now, I do have another idea, that would not only save money, but would
also save a lot of trouble changing all of this.
My present tank is fine, in the sense that it dont leak or anything.
Draining it would not be a big problem, if I did not have to crawl
down in that hole. I already tried to attach a long shaft to the
valve so I could open the valve without climbing down there. However,
because of the angle and stuff in the way, not to mention how to
connect to the handle, this is not feasible.
But, I got another idea. If I could find a low voltage electrical
ON/OFF valve, I could just rig up a switch to open the valve, and shut
it after draining the tank, and do the whole thing from a control box
outside. I know they make such things for hot water heating
equipment, cars, and other stuff. Does anyone have a suggestion where
I could easily and cheaply find something like this. Then, all I'd
have to do is replace the manual valve with this electrical one, run
some low voltage wiring out of the pit and rig a SPDT switch for the
ON and OFF. This pit is only a couple feet from my garage, so I could
run the LowV wiring thru a piece of PVC (for protection), into the
garage, install a 24V (or whatever) transformer in there, and my
switch. This seems like the easiest and cheapest way to solve this
problem, and I could easily drain the tank monthly, instead of waiting
till it gets real waterlogged.
PS. This tank is one of those old tall 40 gallon galvanized ones, and
the pump is a submercible, so there is not way to use any of those
"Air Volume Control" (I think that's the correct name), like they had
on the old surface mounted pumps.
PS2. To avoid the next question I know someone will ask .......
When I drain the tank in the pit, I have a sump pump permanently
installed down there, and simply plug it in to drain the water from
the bottom of the pit. I also have to do that after very heavy rains.
My house does not have a basement, so this is the only place to put
the tank to avoid winter freezing.
