Not so much a DIY question, but something for any plumbers out

It might help us if you showed whats connected to what, and why your locality requires a water tank.

That looks like a booster pump to boost water pressure independent of city or well pressure.

Pretty much the brass pipe is the only thing thats connected and one of the pvc pipes is a run off or overflow drain or something which flows through a sump pump. Theres a pvc pipe off the house which runs into the concrete which I'm assuming is the other pipe? But honestly I don't know.
The brass pipe connects to the house and apparently the plumber said that the taps will spit and spat cause air will be caught in them. So is my water now just running through the tank?

Do you have geothermal heating? I can't think why the PVC goes underground and isn't connected to the bottom to be gravity fed, suggesting they're either return or supply that are pump driven.

No, we use gas so I have no idea.

The plumber had to fill it to test it and to let it bed into the ground.

The lower pvc is the over flow pipe, the higher one will be the rain water in.

The higher copper is the scheme water inlet, the lower copper should be water to the pump.

Possibly a sludge valve at the bottom.

Over all looks like a good job.

> Teflon-tape

It's gonna leak my friend. Maybe not now, but a year or two from now it will

You let some stranger come to your house and charge you money for something you have no idea about? And where do you live that this is required? Not enough info to figure out whats going on here but looks like a nice job. But for all you know, those pipes just go into the ground and the entire system does nothing. Way to be a responsible home owner

it's probably for increasing the water pressure, which is quite common in Yorupoor, given their old infrastructure cant handle proper water pressure without breaking apart.

what BS are you on about?

I have teflon-taped threaded joints in my house, that I made a deacde ago. They're fine.

this guy is correct. it's not a hard thing to do and looks like he did a good job. you need to fill your plumbing systems with water to test for leaks.
>>905586
this guys is a dick, don't listen to him. you use teflon tape to lubricate the threads in order to screw them deep enough to create a seal. threads are tapered so it is the threading that creates a seal. teflon tape and dope are only considered a sort of sealant in low pressure applications like natural gas and propane lines

wasn´t it everything under 3/4" teflon and everything above hemp with fermit ?

>>906841
Many pipe threads are appear to have been machined by drunk children so teftape in residential plumbing often has a sealing effect. I use it for another reason, ease of disassembly for repair many years later. That advantage is also why it's not used for high-pressure joints.
