Removing Whole House Filters


Frequently whole house filters can be very difficult to remove. The canisters become almost impossible to loosen, even after pressing the pressure relief valve and using a housing wrench. The most common reasons for this are the housing was put back on with the housing wrench, debris in the housing threads and a bad pressure relief valve.

How to remove a stuck filter housing.
1. Turn off the incoming water.
2. By-Pass the Softener
3. Go to the nearest cold water faucet, open it and let the water run until pressure drops significantly.
4. Turn the water off at outlet of filter (If housing has shutoff on top off head, turn this off now).
5. Press and hold the pressure relief button to relieve pressure further.
6. Use filter wrench to unscrew housing (If it still won't loosen repeat steps 2-5).
7. After removing, clean housing thoroughly, make sure threads are clean on filter bowl and housing head. Lubricate threads of housing and head with plumbers faucet lube or silicone.
8. Clean and lubricate the O-Ring (replace the O-ring every couple years or if housing leaks after screwing back on). It helps to flip the O-Ring over a couple times per year.
9. Replace the cartridge filter and screw the housing back on.
10. Turn the incoming water on slowly while holding the pressure relief button down until all air is purged.
11. Open outlet and let water run to cold water faucet until all air is purged.
12. Put softener back in service.

IMPORTANT! Only tighten the filter housing by HAND!
NEVER use the housing wrench to tighten the housing.

I hope these tips help you with the angst of removing stubborn filter housings.

How do you change the filter to a culligan water softener


Here are instruction to remove the filter housing. This is from my tips posting. Culligan filter housings are just Pentek/Pentair water filter housings and these tips apply to virtually any filter housing.

I just installed a counter top Aquasana filtration system. Everything is connected properly, but when I turn on the facet and pull the activation button, water begins to massively leak from the handle of...


Well I see from the way this unit hooks up it will put a back pressure on the faucet valve so I would take the handle off and then turn the faucet on with the stem and see where the water is coming from. It is possible that the retaining ring for the faucet cartridge is loose or the back pressure has forced a seal out of place. I know this does not explain why it does it only when it is hooked up but you need to get to the area where the water is coming from.

No flow from EcoWater undersink filtration unit. Flow stopped so we changed two carbon filters and one sediment filter. Still almost no flow.


The water storage has probably lost its charge. A 3 gallon tank should have 7 psi pre-charge pressure. Tank has to be totally empty to set pre-charge. Turn water off to RO, pump air into tank to force all the water out at faucet, turn tank valve off and relieve pressure until 7psi charge.

Why do my faucets leak when I turn my sprinklers on?


THERE TWO CAUSES THAT I KNOW OF: 1. YOUR FAUCETS ARE PRESSURE SEALING MEANING: THEY NEED A MINIMUM PRESSURE TO SEAL MOST LIKELY 25psi, YOUR SPRINKLER SYSTEM IS STARVING THE ENTIRE SYSTEM OF PRESSURE WHICH ALLOWS YOUR FAUCETS TO LOOSE THEIR SEAL. SOLUTION:REPLACE FAUCETS WITH SPRING SEAT SEALING FAUCETS. 2. YOU HAVE A WATER LEAK IN YOUR MAIN WATER LINE AND THE FAUCETS ARE LEAKING AIR BACK INTO THE MAIN LINE WHEN THE SPRINKLERS ARE OFF AND WATER INTO THE SINK WHEN THE SPRINKLERS ARE ON... THIS SCENARIO IS UNLIKELY AND YOU WOULD HAVE OTHER PROBLEMS SUCH AS AIR IN THE LINES AND THE FAUCETS WOULD LEAK WHEN YOU TURNED ON THE SHOWER AS WELL AS THE SPRINKLER SYSTEM.

Is it possible to contaminate the membrane and filters by placing drain under pressure in order to clear and forcing water out the overflow on the side of the faucet of the whre 25 Reverse osmosis system


OK, now I understand. First, on the Reverse Osmosis Membrane Housing Outlet Ports there is only a Check Valve attached to the Permeate (Pure Water) Port, not the Concentrate Port (Drain Water). The Permeate line is what fills the storage tank, so you don't want back pressure from the tank reversing into the membrane filter which could severely damage it. So, there is a high Risk for Sewer Water to Back-flow into the Membrane Filter and Contaminate it as it is discharging water to the sewer drain if there is any noticeable pressure restriction in the drain distribution manifold. Second, this is why "Air-Gap" Faucets are supposed to be used when installing Reverse Osmosis Systems. With an Air-Gap Faucet, there are three (3) attachments for tubing at the base of the faucet, and a small hole drilled out underneath the lever or handle of the faucet. The 1/4" pressurized drain line tube from the RO System attaches to the 1/4" barbed fitting under the faucet base, then a 3/8" drain line tube attaches to the 3/8" barbed fitting. So when the drain water is pumped up to the faucet under pressure, it returns to the sewer line under Gravity, or No Back Pressure. Then, if the plumbing becomes restricted in any way that the RO Unit can't drain into the sewer under gravity feed, the hole drilled in the base of the faucet allows the back pressure to be escaped to the atmosphere, and if necessary drain water out of the hole until the plumbing pressure restriction can be resolved. This eliminates the possibility of a reverse flow pressure situation from occurring. Hope this helps, and you can always visit us online at www.puresafe.com We have filter cartridges for all makes and models of RO Systems, and 1/2 micron filters that no one else in the trade is using at this time. Thanks, Victor
