Hi all,
A bit OT but hopefully a few of you will have come across what I'm after.
I have a ridiculously over-engineered watering system to water my balcony gardens, and when I'm only watering one section the pump is way too over-sized and the pressure cutout setting means that the pump is starting and stopping more often than I'd like.
Rather than go down the route of a VSD pump to lower the pressure, I thought of using an adjustable pressure relief valve to circulate excess water back into the tank. Something like this one. Only thing is, this one is about $A500-$600, and if I was going to spend that sort of money I'd just put a VSD in and do it properly.
Does anyone know of a more entry-level/domestic market pressure relief valve? It'll need inlet/outlet ports somewhere in the range of 3/4" to 1", and adjustable pressure somewhere in the range of 50kPa to 300kPa.
