i'm don't know to be honest i'd guess yes.
where did you buy from?
I know varitech are good for these types of things, also gardiners (maybe)
window cleaning warehouse, grigs, cleantech.
I feel your pain my ro sytem froze, it's at my parents in their garage, so can't keep an eye on 24/7.
the 3 pre-filter housings all shattered. (ro-man gone bust so can't get exact fittings
)
got new ones from wcw, trouble is don't fit straight to ro-man system, had to take apart and alter, fixed em today at home and will try at parents tomorrow
Nearly run-out of ro-water
once my tanks full 625ltr will disconnect ro-system and keep indoors toasty warm
