Pace 3: Troubleshooting

Once you've identified the source of the leak, you lot tin can figure out why the system is leaking.

Common causes of leaking include incorrect installation, filter housing that'southward been over- or under-tightened, faulty o-rings, loose valves, drain line connection and incompatible adapters. Hot water or loftier water pressure can also damage nether-sink water filters, causing leaking.

Stride 4: Resolve the Effect

Finally, in one case you know the crusade and the location of the water filter leaks, you tin resolve the problem earlier it gets whatsoever worse.

Hither, we've outlined some of the virtually common causes of leaking nether-sink water filters and how to set up them.

Over-Tightened or Under-Tightened Filter Housing

When installing an nether-sink water filter, it's important to get the right balance betwixt under-tightened and over-tightened filter housing. Both extremes will cause the filter housings to leak. Over-tightening is especially dissentious because it tin cause hairline cracks on the threads or in the filter sump, or crush the o-rings.

To resolve an issue caused by under-tightening, use a filter wrench or hand-tighten the filter housings until they're firmly in place, without forcing them any further.

To resolve an over-tightening leak result, check the threads and o-rings for damage, and supersede them if necessary.

Every o-band in your unit of measurement should exist cleaned, lubricated, and replaced as necessary. A faulty o-ring is the cause of most leaks in an under-sink filtration system, allowing feed h2o to escape from the housing. Make sure the o-ring is seated properly in the housing, too, as an improperly placed o-ring is another cause of leaks.

Y'all should simply ever use silicone-based lubricants to lubricate an o-ring; never petroleum jelly, as this will eventually compromise the seal.

Don't Over-Tighten the Filter Housings

Y'all shouldn't apply excessive force when you're tightening the filter housings. Only employ your hand or the plastic wrench provided to do the tightening. This will foreclose issues like bound leaks caused by cracked sump housing.

Bank check your System Regularly

Finally, make sure to check your under-sink filtration unit at least in one case a week to make sure everything looks normal. If yous have an RO arrangement, cheque that the water storage tank looks in good condition and double cheque the connectedness to the drain line. If your filtered water starts to sense of taste different, supplant the filters before leaking can occur.
