I'm just starting up on the wfp trolley system (bit daunting really) i know nothing about it just what i can glean off this site  Regarding TDS reading my tap water is 087 is this high or low ? do i need a RO or DI vessel thing ? sorry if i sound a bit thick to you guys, got a trolley now so just need a pole/brush and the pure water sorted. hope to be up and running soon and get confident with the whole thing. thanks in advance.

thats pretty low mate, youd get away with just DI

Their was a poll on here a while ago about at what tds level people used di/ro
it was generally that anything below 100ppm was di any above it was ro as you probably wont be using loads of water then i would reccommend di if water usage was high then an ro would then start to be cheaper
Hope that helps a little
Oh and good luck with the changeover to wfp

Nationally, a TDS of 87 is considered low.  It's almost the same TDS that we work on down here in Cornwall.  Even with a TDS of 87, I would still recommend an RO System to purify your water.  This will bring your TDS down to about 001-003 (depending on RO used).  A small resin canister as a final polish will bring you to the ideal 000.  The comparitive costs for running a 1 man system on a full time basis using an RO System will be about 1/4 of that for running a resin bead system. 

A cheap RO System (RO-Man 200 gpd) does not cost much more than a sack of resin and a decent resin bead pressure vessel.  Of course, if you don't have the space for a storage tank and an RO System, then a DI resin system does offer an easy alternative.
