Product review (5 stars): Like other(s) said, fixed my TrueSTEAM shutdown problem & at a good price
Really just a ditto of what other reviewer(s) said, fast delivery of item & fixed same problem.  I'm also tempted to order a spare to have around.  Easy to install & makes the repair as inexpensive as it can be.  Now if the TrueSTEAM didn't suck down so may kWh we'd be good to go:)

UPDATE:  Though this item fixed the problem back when I wrote this review, our TrueSTEAM has self-destructed (1/2016) like they all seem to do after 3 - 6 years.  Had 2 problems in the same month:
1) plastic reservoir itself started to seep / drip (not the seal, a temp stress / age crack at bottom)
2) the water inlet valve let H20 continually enter.  This caused extra hot water to slowly flow down its outlet tube.

So time to remove & toss this POS TrueSTEAM into the trash.  Installing an Emerson HSP2000 since it appears an easy DIY job & uses same 120V elec + H20 feed, is made of metal & has good reviews.
