nakedmolerat:

holy heck at the number of pump(s) you got there! +1 for Davey.

btw, i was thinking about uv filter for our rain water tank (used for cooking/drinking etc), i read around it and it looks like a 'scam'. we just have the simple cheapie water filter. no problem lol.

Looking at another one and another 22,000l tank. 

We have a couple of full-house filters (10"x4.5")... a washable 20 micron filter and a 5 micron coconut carbon block. I drink it, but the Mrs wont, and when we need the river water, it's pretty brown (I wont drink that) :D

Going to change to a triple 20"x4.5" setup. 20 micron washable into 5 micron polyspun washable sediment and finally, the 0.5 micron tannin reduction carbon block.

@Aredwood: I have 3 pumps as part of my main rainwater system. Plus various other pumps for secondary tasks. And this is all on an suburban property.

Got me intrigued...

What's the reason for your setup? 

Thanks for the suggestions guys. I have contacted Davey and they have suggested

XJ50T for toilets/washing machine ($864 excl GST):

HM60-08T for showers, taps etc.

Neither seems to have VSD but they don't think I need it. They have suggested each has a 8L pressure tank also. I am wondering to go with a smaller model for the toilets but the cheaper model doesn't have the Torrium controller but "pressure switch". Would this be OK to just have a pressure switch?

This is like half the price of one with the torrium controller:

Torrium is sort of the same style.. Variable pressure as needed. From what I've read, it adjusts the voltage the pump gets (so the pump becomes variable speed) and since the davey pump is designed for it, no issues.

My main house pump (davey XP700h) just has a basic pump controller but it's adjustable, and we don't get cycling. The torrium controller is double the price, and then some :)

My stupid broken pump has a pressure tank (not really needed) and so does my river pump. Since the river pump is on a timer and is filling a 15,000l tank, the pressure tank is a bit pointless :D 

Plus there's only 2 of us and we never have any issues with pressure (the toilet is on gravity from the big river tank) but when it finally does need replacing, I'll go the torrium 2. 

Sorry if none of this makes sense, I spent 80% of my day fixing a powerpoint presentation that was about fire appliance pumps and how to operate them (I build fire trucks for a living), so my brain is fried (and I'm probably getting pump stuff mixed up everywhere) I'll probably edit this later.
