7/8/18  reused grease so next time order some!  Other notes.  Remove the hoses first with a channel lock wrench.  let water drain, flip over with the “top” down on a foam pad  (new technique).  Mark the position of base and cover to guage the unsrewing process. Use bar as before, and hammer to tap the base threads loose counterclockwise looking down at the inverted unit.  about 3/8″ of circumference and the threads will be loose. The foam pad holds the unit enough so didn’t need any help.

7/13/16  Installed water filter today.  Took about an hour and several tries to get the fit right.  Flipped the filter over to the correct way with the input/output flow tubes at the bottom rather than the top.  Lubed the o-ring prior to installation. Also used the seal on the filter gasket supplied with the filter.  The cover was screwed on 180º too tight and this time I determined that much tightening was 175º too much.  Pretty sure now that amount of over-torque was unnecessary if not a bad practice. Note also the use of Dow Corning o-ring lubricant and seal.  Oh yeah – cleaned up the area a bit. Much better.

Our water filter was the original Amway full size from Alvin many years back now.  The filter is a 0.5 micron filter for  lead, chlorine and trihalomethanes – probably carbon block type.

  • Reduces fine sediment, chlorine taste and odor, and protozoan cysts in residential and commercial drinking water
  • Nominal filtration rating of 0.5 micron

Installation notes.

The bottom cover screws in and has always been over-tightened. This time: hand tightened to full tight, then torque to about 1/2″  over torque using the crowbar for leverage and tapped with hammer.  I put markings on the cover as a guide.  The water/pressure seal is obtained by the o-ring and the sealant is a critical part of this design. Water should not be able to push past the o-ring.  The purpose of the threads is to seat the o-ring seal. It may serve a compression purpose, but seems like a super torqued threading should not be necessary.  In case compression is required, for leverage,  I used a 15″ crowbar and tapped with hammer to remove and to then re-torque the cover.  The crowbar work well.

  1. Lubricate the o-ring by coating the o-ring generously with the  DC Molycote 111 sealant and also in the o-ring seal area on the tank.
  2. lubricate the seal washer on the bottom of the filter cylinder threads and tightly screw in the filter to the bottom cover assembly.

Until next year ..

About Dow Corning Molycote 111 – heavy consistency

Dow Corning Molykote 111 Compound is a one component, silicone oil that is used for damping, sealing, and lubricating outdoor equipment, pressure systems, electrical equipment, and used as an anti-stick. It provides low volatility, low vapor pressure, wide service temperature range, and water resistance. 150 g Tube.  {next time, store it in the base !!}

Other applications: Lubrication for control and pressure plug valves, water softener and faucet valves, sealant for vacuum and pressure systems, chemical barrier coating, rubber and plastic O-rings, gaskets and seals.

Tier1 OR-LUBRICANT-LG Food-Grade Silicone O-Ring Lubricant helps to provide a good seal and to prevent water leaks on all brands of water filter housing o-rings, in addition to preserving the integrity of your o-ring. You can reuse your o-ring as long as it is not damaged. Silicone Lubricant is safe and easy to use. Other types of lubricants are not recommended for o-rings, because they can actually stretch and distort them. Silicone Lubricant can be used for a variety of applications, such as cameras, scuba gear, and pressure valves. Provides a chemical barrier coating, with low volatility, good resistance to most chemicals, excellent resistance to water, and low vapor pressure.


Amway water filter replacement

Posted in Uncategorized with tags on February 23, 2014 by marksun

Time to replace the AMWAY water filter Uncle Alvin gave us way back in the day.  Every year or two (yikes) we do this.  We’d order the part from Alvin’s son Pono, who would come by to shoot the breeze and install it.   Always an interesting conversation – ask me about  Kamehameha sometime…

The fun part is getting the filter apart.  

Needs some cleaning where the hoses attach …

Removed hoses and marked the dark colored hose nut hose with blue tape.

Found the steel bar I used in the past for this job under the sink.   This is used to wrench apart the filter holder and the reservoir housing.  Counterclockwise to loosen. Left loose, Right = tight. Two man job – one to hold the case using a length of heavy nylon strap ( dog leash ) + WD40 did the trick.  Used small amount of silicone grease on threads and o-ring.

Water goes into the reservoir and pressure forces the water through the filter into the center outlet coupling.  Any contaminants in the reservoir must go through the filter.  Wd40 was washed out thoroughly.  Any residuals will be trapped by the filter.
