Can the Rain Bird PSI-M30X-075 3/4 in. 30 psi Inline Pressure Regulator be installed ahead of a manifold to regulate 6 stations?
A shopper on Aug 18, 2014
BEST ANSWER: It could be however i would check to make sure the GPM through each zone does not exceed the GPM through the M30X. I install these for drip irrigation using the Rainbird wye filer. each drip zone is controlled by the valve at the manifold. I run up to three drip irrigation stations from one valve. More control and less $$$.
I have a water source directly from meter to hose bibb. Then hose bibb goes pvc to back flow preventer and then on to timers. Water pressure at back flow preventer was tested at 135 psi. I would like to reduce this to about 60-70 psi. Is this regulator adjustable within this range? Does this regulator have a built in filter or will I need a separate filter between regulator and back flow preventer?

Can the regulator be buried underground inline with irrigation system?
A shopper on Feb 26, 2016
BEST ANSWER: I have mine both underground and in valve boxes. Where they didn't fit inside the box I burried them just outside the box. I have eight valves running off 2 house external taps at 72psi. I needed to lower the psi to 30 to work with the rainbird MPR,VAN nozzles and my drip system. They just have to be downstream from valves.
Where does the regulator get installed?
A shopper on May 24, 2013
BEST ANSWER: The short answer is always after the valve and before OR after the filter.

Additionally.....Some professionals install them after the filter so the water going through the regulator has already been filtered (decreases chance of sediment damaging the effectiveness of the regulator) and you don't experience additional pressure loss due to the filter because you likely still have higher pressure after the filter than you are stepping down to with the pressure regulator. Other professionals install it before the filter because, though quality filters are designed to withstand the pressure spikes experienced by parts installed before a pressure regulator, a pressure regulator is better at this and has less threaded joints that can leak under high pressure and/or improper teflon taping (2 threaded joints vs. 4).

As long as you install both your filter and your pressure regulator after your valve and in the correct direction for flow (see arrow or each part), then you can put them in either order for the desired pro's and con's.
can I get a CAD model for this PSI-M30X-075 please?
I also wish to know whether the materials it is made of might get affected by a 0.6M phosporic acid solution or a 0.4M Sodium Persulphate solution.
