We bought a new home about two months ago that has a Viqua water filtration system installed. To ensure everything is new and up to date we purchased UV lamps, castings and filters and performed a full system clean. We installed a new UV light with moldings and filters over Labor Day weekend and yesterday the alarm in the system started ringing. After reading the book and calling tech support they said the UV lamp was not working. We took out the UV lamp and it burned out. We have had UV lamps in the past and they should last at least a year or more. Very disappointed that the $50 UV lamp and cast burned out within two weeks. Now our system is not working for our well water and I have to contact the seller to see if there is a guarantee, it would be better!
