once you hold made the repair, send the outmoded cartridge into Moen for a free videotape replacement.
you will now enjoy a replacement cartridge for the subsequent time and will now be versed contained by repairs.
Answers: Generally speaking they are guaranteed for lif. The drawback is, I hope you kept the receipt or proof of purchase!
