Fountains in a pool deck

If I run a 1 1/2 pvc line to 4 different jets in a concrete pool deck will all 4 receive the same water pressure

Welcome to the forums.

If the supply line is charged to a certain pressure...... yes..... all the four identical jets should receive the same pressure. In the event that they weren't identical....you could install trim valves right at the jet location for slight adjustments.

Maybe

For example, if the outlet jets are rated at 2 cfm and your supplying 10 cfm then they should all be the same since you are providing more than they use.

If the jets are rated at 4 cfm then the closest one will get it's full shate and then down the line until the last one has nothing!

It's sort of a complex question to answer. Best is if your four jets all have orifices to limit the flow to less than what is supplied. That way the piping will pressurize and they will spray about the same amount. They won't be exactly alike unless you worked hard to make sure each jet has the same length pipe and fittings so they are all balanced, but if they aren't identical it should be relatively close.

Worst would be four large jets that all together can flow more than your supply. In this case you will have to be very exact to make your piping to each jet identical. Any variation will cause a different flow to different jets.
