Has anyone seen the bladder type water pressure tanks for sale in DR.
I can get a 14-gallon for about $160, but getting it shipped would be costly becuase of size and weight.
Bladder types are much more consitant pressure that the tanks I see sold here.
Where have you seen them sold ?

I'm surprised you can't find one. Ochoa and Americana still has them.

Jeeze, they used to be available everywhere. Even small ferreterias used to have them. I bought one in Americana and they had like 8 sizes.

Not that expensive eithejr-I think back then the smallest was 25 gallons, IIRC..

Do a search for "Tanque de agua con diaframa" and see what pops up.

They are called tanque prepresurado and I see some but I hear they're available in Puerto Plata

Does the tank reset it self and resume the water pressure after a electrical outage? And/or does it hold pressure for any length of time?

They have a bladder with a valve stem that can be pressurized slightly with a pump - think like an inner tube. As water enters under pressure it compresses the bladder which maintains pressure in the system after the pump shuts off.
Most have no bladder and the water after time absorbs the air and the pressure doesn't hold until you drain the tank - then it pressurizes for a short period.
Almost all wells are services by a bladder tank

Thanks.

I saw the equation for determining the size. Did you do that yourself...or assisted by a plumber?

Another great thing about them is they only require one tube that functions both ways.

The ones I've seen have only one hole in the bottom with a "T" installed, and install it inline to the house. Put a check valve on each side of the "T". Simple installation.

Bladder Pressure tanks work well maintaining constant water pressure with demand. Yes they are inline to the demand line, and work with electric pressure switch to turn on/off pump.

Now I started to see electronic pressure control that are " in & out" of the demand line. Do not need electric power switch to turn on/off pump.
Has anyone have experience with these "electronic pressure control, do the keep water pressure stable as the bladder tanks.
