Default Water Filter Filter Replacement..."STUCK"

Hi All...I have a whole house "Omnifilter" filtering the sediment from our well water...we live in the country. I had some plumbing work done and had them put in a new Omnifilter (brand name). This is one of the plastic sediment filters with the drop in cartridge...very common.

The new filter unit is difficult to get the plastic cover loose when you wish to change the drop in filter. Well, now I cannot get it loose at all. It comes with a plastic "wrench" which fits lugs on the unit...but even if I apply enough pressure to risk breaking something it just won't come loose.

Any ideas?

What about appying heat with a hair dryer to the outside of the unit...might that either expand the outer case and/or "break" whatever "seal" is holding?

Any other ideas on getting this loose?

Also, has anyone had this problem and found a way to not repeat each time...maybe vasaeline on the threads? I used the white plastic "seal" tape on my previous unit and it worked fine...maybe that isn't helping on this unit?

Any suggestions will be appreciated...don't want to break it...Tom in Two Harbors, MN

Tom,

Try a LITTLE heat on the cap. Too much and it will warp. Once you get it off, use beeswax on the threads after you have cleaned them. The wax will not come off easily and will not harm anyone if a piece does break off. I have also seen guys use candle wax on these also.

You might also try tapping around the perimeter with a small dead blow to break it loose. Just don't get crazy and break it....

Make sure when you reinstall the housing to only hand tighten it too. I have the same set-up in my house. It is kind of like an oil filter on a car. Hand tighten and you will still need the wrench to loosen it. I use a a little plumbers grease on the threads too.

I hate to state the obvious, but make sure you have shut off the supply line and depressurized the lines or depress the pressure relief button on top of the filter otherwise you will never move the housing.

As stated earlier; upon reinstalling use some plumbers grease on the o-ring and threads. Don't use Vaseline as its petroleum based.

Tom,

Nah, I haven't been talking to yours, I have one all to myself that I have to listen to..... I think they all come pre-programmed to offer that response... It ranks right up there with "Are you sure you know what you are doing" or "Don't you have enough tools? What is THIS one for?"

Relatively gentle hammer assist on the plastic wrench did the trick...did not get to the heating stage. Thanks all.

Plumbers grease (along with careful hand tightening) seems like the easiest answer?? I assume most heardware stores would have "plumbers grease"? That isn't the grey stuff is it???

Thanks...Tom R

This is what you want............

http://www.herchem.com/specs/plumbers_grease.pdf

You can get it at Home Depot, Ace, True-Value, etc...........Just smear a light coat on the threads and o-ring and don't go all gorilla monsoon when you tighten it back up, the o-ring does the sealing.

I have a similar unit, with similar problems.

If you are doing it right, then you are lubing the O-ring with vaseline, go one step furter and lightly coat the threads of the filter housing with vaseline too.

It helps. Tremendously!

As for the stuck filter you have now, get the proper wrench. It will come off, if not by hand, with the help of a rubber mallet tapping on the end of the wrench.

Thanks All...got it loose by tapping on the wrench with a mallet...will add plumbers grease to threads and o-ring...and NOT "just tighten ONE more time! " Appreciate the help. Tom R in Two Harbors, MN...currently light snow!

I too have been using vaseline for the last 5 years and have never had a problem with it. I also coat threads like IDASHO. Here in Florida it is currently in the 80s here.

Vaseline, being a petroleum based product, has the potential to break down some types of rubber seals. Perhaps not the ones in your system. I am unsure of whether it can contribute to water toxicity or not, but I'm not taking any chances for the sake of a few bucks.

Vaseline is recommended for use by the manufacturer of these filter systems.

I stand corrected if this is true for the Omnifilter, but others should be wary since not all manufacturers are the same. My Envirogard filter specifically specifies a silicone based food grade grease. Obviously the manufacturers recommendations should rule.

AHA! Hold on there. I was wrong.

I just rechecked the user guide that comes with the filters (I use OmniFilter T01-SS)

*Lubricate O-ring with clean silicone grease. Reassemble housing and hand tighten.


Ive always used vaseline though... and Im still alive

I just use Silglide on mine. I use it for all O rings. Napa sells it, about $5 for a tube.

My filter housing is also very hard to remove. The plastic wrench that came with it slipped and deformed so it's useless. My 12" tongue-and-groove pliers are a little small. I was thinking of getting some 16" Channellocks that only cost about $22 at Lowes. Hopefully they would be big enough.

I have the same filter and they are a pain to remove if there is any pressure on the system. I use http://cgi.ebay.com/ws/eBayISAPI.dll...&category=1267 on my housing, works well and is safe.
