1000L Mauzer Tank for Pressurized Water in Basement Plastering: Hydrophore or 24L Compressor?

Hello. I have a throat situation. In 2 weeks they come to do plastering in the basement, today I got an appointment from the waterworks to connect the water on November 20. I have to somehow get pressurized water to the plastering machine. I have a 1000 liter tank under the roof gutter. What is the easiest way to create pressure in it to ensure proper operation of the unit? I was thinking about a hydrophore that I would have to buy. I also have a 24 liter compressor pumping up to 8 bar. I wonder if it's not too much for such a tank, will it last? Anyone have any experience?

acc. this video, this is what an IBC looks like at 4 bar: https://www.youtube.com/watch?v=-dBNouZ8xH0
It doesn't look good. In the water supply network, the pressure is often below 3 bar, and the minimum is probably 0.5 bar. So the chiller should work properly when the pressure is 0.5 bar. I would add to this another 0.5 bar for resistance in the supply hoses and changes in the working height of the unit.

This tank can't handle any pressure.

I used to pour water into it without a frame, at 300 liters I was afraid that it would burst under the pressure of the water column.

You need at least 2 bar for the plastering unit to work properly. There is no way without a hydrophore.

Maybe a neighbor will give you a water tap.

I'm too far from my nearest neighbor. Why won't it withstand any pressure? I have a tank without a frame and it was often filled up to the cap and nothing happened. Even one winter it froze - it got bigger but did not crack. I think that the pressure of 3-4 bar would easily withstand the current consumption. I would turn on the compressor only when unscrewing the water drain valve .

Maybe a submersible pump will suffice? They are relatively cheap.

I have such a pump, but it will not go through the tank opening. I also wonder if it will generate the right pressure if the tank is, for example, 1 meter lower than the aggregate. By the way, does anyone know how much water such aggregates consume depending on the type of plaster in converted into kilograms or square meters of plastered surface?

The bag must say how much water is needed

Fact. I didn't think about it. I'll check it tomorrow. I mean how long will these 1000 liters last, because I won't order rain

On one page I read that the consumption is about 16 liters per 30 kg bag, plus some amount of water for washing tools.

On this website www.tynki-fachbud.pl/faq there is information:
"The average water consumption is approx. 1000 liters per 100 m2 (cubic) in the case of gypsum plasters. When it comes to cement-lime plasters, the water consumption is much lower and amounts to approx. 500 liters per 100 m2."

A tank without a frame will probably be much less pressure resistant.

If you have a submersible pump, the one from the market that raises water up to 5m, it will be too weak.
I found on Allegro a pump for deep wells with a minimum hole diameter of 110mm: HECHT SUBMERSIBLE WELL PUMP with a power of 600 W. Max. lifting height 70 m. This one looks sufficient.

For cooperation with aggregates, the following pump is recommended on several pages: AV 3000.
It has the following parameters: 600 W, pressure 5.5 bar, capacity 3000 l/h.

Strap the tank around with a strap with a tensioner or something similar.
It will definitely withstand these 3-4 bars, unless it has a defect.
I bought two such used tanks for PLN 100, so where to pump / hydrophore.

How many meters of plaster do you have to do? You're not going to wait for the rain to continue plastering, are you?

350 square meters to be plastered. 2 tanks already filled. Tomorrow I will install a hydrophore. Regards.

As I said, I installed the hydrophore and am waiting for professionals. The hydrophore is Einhell with a capacity of 20 liters. It turns on at a pressure of 1.5 bar and turns off at 3.5 bar. After unscrewing the valve behind the filter to the max, the hydrophore maintains a pressure of 1 bar and pumps all the time Is it possible to increase its efficiency? Which knob is used to set the switch-on pressure and which is the switch-off pressure?




The last photo shows the back of the compressor with the pump drawn and the indicator 1.5 bar. I understand that this is the pressure inside the tank. Can it be increased? Where to pump it, will it increase the efficiency of the hydrophore?

If you have 1 bar at full opening, you won't squeeze out more, unless you choke the valve. You regulate the pressure and hysteresis of the pressure switch with nuts painted red, the larger spring is responsible for the activation pressure, the smaller one for the difference between switching on and off. Under the black cap on the hydrophore tank you have a valve, just like with the tires, with the pump turned off and the outlet open, you should blow the pressure there by 0.2 bar lower than the pump start pressure, it will not change its efficiency, as well as the regulation of the start and stop pressure.
