For "What it's worth" department

I would be careful with 75 PSI setting with Dominican plumbing. The PVC tubes are rated for 80 or more PSI but my concerns would be with the Joints. Most plumbers here use that Blue cement/PVC glue and its medium grade especially when their no primer apply first.

If you can adjust the PSI setting, 40 PSI is more than enough.

Duly Noted.

without power water flow is very restricted, not zero but much less than simple gravity. It does have a no water shut off sensor but mine on one occasion kept going. don't know for how long it went but I heard it humming and shut it off.

Correct. I always have electricity so no problem there.

This model can run without water without being damaged.

In my case, I am usually home and would notice if there was no water.

 

[JD Jones]

Ok, I may be a bit dumb, but it is only useful when you have no main water pump, right ?

Otherwise one would just use the main water pump when they want a hard shower.
At least that's what I do.

Or do as the " regular Dominican " would and use the ladrona pump.

Our building has a main water pump that sends water to the apartments and the water tanks on the roof. That pump is turned on 3-4 times a day to keep the water tanks full. I do not have access to the main pump switch.

I am using this pump to augment the pressure in my apartment.

I have two ladronas,(not connected after trying them and not being impressed) but they do not have on-demand switches.

This little guy is pretty much plug it in and forget it.

JD, I read the spec on your little pump. Be careful when connecting seem to come with "hose tread" and the pvc tubing here comes with NPT (national pipe thread). You may need an adapter.

I can explain more if you do not know the difference.

Thanks. I went through that a couple of years ago with another project of mine.

This little guy in up and running and I've got another on the way, just in case.

Good, let us know how it goes in a few days. It should work great as all this pump is doing is pushing water. When a pump is sucking water from a height then it forces.

None left on amazon, you bought them all. Just like at Jumbo empty the shelf because do not know when there will be more. HaHa

Be sure you're looking at the right configuration. There are various versions. Also different vendors selling the same pump.
There are also quite a few other pumps with a different name but it's the same pump.

Hey JD, this is very interesting, perhaps I'll install the same pump in my house later. Can you make some pics when you've done the installation of the pump.
Thanks

It's a little tight where I've got it. It's the same setup as post #10.

Ok, so it;s inside your apartment?

Yes.

Yes removing the pressure tank and old switch is a great idea. You can get this here as well.
The pump starts and stops (Providing its full pressure capacity) when you turn on off the water. a 1/2hp truper works very well. View attachment 8796View attachment 8797

Where did you purchase the ¨Truper Expert¨ pump?

 

[JD Jones]

A quick note: the pump has been working perfectly. One thing I have realized is that the pressure adjusts to the demand.

If I open the faucet just a little bit, the pump runs very slow. The more I open the faucet, the faster the pump runs.

I've got another one I am going to install on my hot water heater so I always have great pressure when I take a shower.

Pardon my ignorance, but what is a ladrona pump?

Not the real name for any pump.

Any small water pump that is given that nickname because Dominicans use small water pumps to "steal" water from others when the water supply to an area is activated. .

Fascinating way to see that JD! Yes the Doms call it a ladrona, but the intention I doubt is to steal water, but pull the water when in limited supply when the pressure is too low. A small Truper costs less than 1/2 case of rum, so if the Doms call it a ladrona, it clearly is a priority issue

It seems like that pump kicking on and off every time you open a tap or flush the toilet would shorten the life of the pump(?). That's the reason there are accumulator tanks on most systems.

 

[Notengo]

That’s a nice solution. Especially if you can tune the pressure threshold.
I notice many tank pumps still turn on every 10 minutes or less just because of loosing a little pressure, are these not adjustable?

Those systems with sensor automatic turn on cost significantly more $$$. Most lower income Doms they have a pump and when the city sends the water they pull it out of storage, hook it up and fill their repletos, whether it be the big 50 gallon blue tanks or a tinaco.

Adding: or in some cases a legion of smaller buckets and if you’re lucky a few repurposed 5 gallon paint bucket

Mr cavok its 67 usd who cares if it shortens the life of the pump
