Installing a pila for the first time
I will be installing a 450 liter pila about 8' high in October, cabin has 1 bath and 1 kitchen sink. This is my first time and I've noticed many
different ways of plumbing them. I intend to have a 12 volt demand pump to increase pressure. The water will be trucked in. Any suggestions? Can
the pump be located anywhere between the pila and the first faucet? I've noticed 2 types of PVC being used: regular 1/2" and a smaller pipe, looks
like it's about 1/2" on the outside.
Thanks
Oh- saw the pilas at Home Depot in Ensenada for $900 pesos.

I was looking at those Rotoplas tenacos yesterday. I might be using one beneath the house for gray water. The 450 liter tank I saw was 4' tall. What
did you see that was 8' tall? Is yours going to be a gravity system with a demand pump booster? Is there any reason you wouldn't use a larger tank?
125 gallons won't last long.
Where are you located?
Do you have electricity? I'm guessing...no.
Use 3/4 inch, schedule 40 PVC.
How large is the water delivery truck, Pipa, in your area? A standard load in my area is 2500 gallons.

Dennis,
I'm sure he was referring to the height above ground of the installation not the dimension of the pila.

If your using 12v dc as a rv uses one half inch pvc is plenty big
Make sure there is some kind of vent so air can get in the tank
Its best if the inlet on the pump is below the tank so it floods the inlet
The out let of the pump should then be plumbed all cold water uses and the water heater
From the water heater to the valves you should use pvc for hot water
Be sure to put a switch in a handy place to turn off the 12 volt when your gone

ps the inlet to the pump should have a gate valve in it so you dont loose all your water if repair is nessary be sure to turn this valve all the way
on when in use

If I can stray just a tad here, I was looking at these tanks in the ensenada home depot. Some are black and some are a tan color. They seem identical
but the tan ones are about 20 dollars more. whats the difference?

To answer your question, "Where to locate the pump" It's always best to locate the pump nearest the source or supply. This makes it easy for the pump
to draw, and then it can push the water anywhere.

Your booster pump will have predetermined sizes...most RV are 1/2"...I/O
Hard to give good advice...all installations are different.
From your pila to near pump inlet use any size... larger is better...reduce to 1/2" near inlet. Outlet must remain 1/2" to each deliver point...the
larger the water column on outlet side, the more amps it requires to deliver the supply. Also locate the pump at the point you intend to "Y" to hot
water tank...to reduce the distance it pushs in each direction. It is true to locate your pump near pila...pumps push better then draw...a large
supply line will answer this problem. again I do not know the distance we are talking about...
Copper pipe should be used out of the hot water tank and it helps to insulate it.

if you're using a pump...why put the pila 8 feet high???
remember when you "feed the beast" you'll need to get the water up 8-12 feet
you or your delivery guy will need a gas-pump to "pump-it-up"
why not put the tank on or in the ground...
water weighs 8 pounds a gallon
that stuff is heavy
it's alot safer to have the weight on the ground if something breaks
and water falls much easier than it climbs
lot easier to work on too...later when it breaks
ALWAYS use 3/4 or one inch
you'll get MORE water to the sink and shower
1/2 inch won't give you any distance
you'll have a Dibble on the other end

PVC Pipe
The smaller diameter pipe may be CPVC which is usually used for hot water applications. I believe that pipe is measured by OD. In any case, CPVC 1/2
or 3/4 IS smaller in diameter than PVC.
I have had CPVC in use for Hot water applications for 20 years without any problems at all. A lot easier and cheaper than Copper. In many U.S.
locales, including California, it is approved for residential use.

If you have a pump, be sure to have a turnoff floater in the tenaca so you wont burn your pump up if the water runs out.

MrBill is correct...cpvc can be used...don't know about availability. I am old school and don't like it because of size and real tough to pre fit...I
can string long runs of copper and then solder without didassembly....means nothing depending on conditions.
A link if you really interested...
http://www.buildings.com/articles/detail.aspx?contentID=3421
The advantage to height is head preassure...no power it still give water. depending on how it is installed...may not need pumping for most
applications...demand switches will also conserve DC power...assuming you need to. effectiveness of RV pumps is in the installation... Another link:
http://www.shurflo.com/pdf/rv/Euro/RVEnglishA4.pdf
In 12/24 volt installations you may need to use dual pumps.
EDIT: I do remember the words Cabin...1 sink...! shower and I assumed this was an off grid installation...

I agree, Bob, but maybe it's just for very limited use. Who knows. Santiago is AWOL. We need more information if we're to properly confuse him.
