Housing Cover O-Ring Replacement

O-rings can wear out after extended use. As a key to preventative maintenance, we recommend having a replacement set on hand. Housing Cover O-Rings order quantity of 2 for these models: AlkaRev™, Revolutionizer™, RO Accessory Unit™, Under Counter Revolutionizer™; order 3 for these: AlkaChi™, AlkaDirect™, AlkaPurity™ H-D, AlkaPurity™ PRO, AlkaPurity™ Ultra. While it is almost impossible to predict when an O-ring will fail, there are good rules of thumb to use. First is that when servicing an item that has an O-ring installed, look at the seal to determine if there is any cracking or hazing due to degradation or damage. Second, when servicing an item that contains a seal, if you can see it, you should replace it. Wouldn’t it be a shame to lose the use of your System for a week while you wait for new O-rings to arrive when you could have replaced them in minutes? To do so, remove the O-ring so it, and its groove, can be wiped clean. It’s a good idea to put a little Vaselin
