How do i disassemble Delta Innovations Centerset

Remove the handles. See if the chrome slip nuts holding the stems in are corroded. If they are, the cartridges may not be fully seated or the o -rings that seal around the cartridges may need to be replaced. If either of these is the case you can tell for sure by turning the stems to the on position with the handles removed and looking for water seeping around the cartridge. If none of the above is the cause then check to see if the aerator (screen on the spout) is loose or corroded sending a light spray back towards the faucet body that looks like a leak. If this is the case remove and clean the aerator, then reinstall it making sure not to cross thread it. If none of the above, replace the faucet. Be sure to call Delta first before replacing because they have a lifetime warranty and you just might get your faucet for free!

If you notice right below the handle,there should be a small opening where ,by using an allen wrench you should be able to remove handle giving access to the stem retaining nut ......CAUTION... be sure cutoff valve is turned off(both hot and cold cutoffs.... under lavatory sink before removing..........unscrew retaining nut and remove stem.....hope that helps......

You may need to replace the stem unit assembly.

Check outside water pressure to house. Should be 65 - 75 PSI. If good most likely the cartridge. Older faucet, do both sides to prevent future problems. Blade handles? Make sure you get Hot & Cold stems, they turn the opposite way with blade handles. Some cartridges are universal and can be adjusted to work either way. After removing the stem, check with a flashlight in the valve, delta has rubber seats and springs on many of their models. If so, replacement of the rubber seats may do the trick.

Many of these problems develop from poor maintenance on water heaters and high pressure. Water heaters, regulators, safety valves, supply lines, and emergency shut off valves at fixtures should be checked, cleaned and adjusted on an annual basis. Your local expert plumbing contractor should be able to assist you on that.

Moen Monticello 4-inch centerset bath faucets can be repair easily with only a screwdriver and adjustable wrench. Turn the water off to the both sides of the faucets under the sink. Open both the hot and cold-water valves to alleviate any remaining pressure. Remove the handles by grasping the base of the handle and turning it counterclockwise.( This works for both lever and cross handles). Loosen the Moen faucet cartridge bonnet nut with an adjustable wrench by turning it counterclockwise to the left. Pull the stem from the faucet by hand and replace. Reinstall the bonnet nuts and handles. Turn the water back on and test the faucet for leaks. The Moen Monticello faucet comes with a limited lifetime warranty. Try calling Moen to get your replacement parts free.

check the angle stop under sink as sometimes the washer gets lodged in the orifice to stop..make sure water is off to house before removing handle to stop...check the hose...then the stem and seat to faucet itself.

First turn water off to faucet and remove the screw that hold's the handle in place. They may have a cap on the handle to remove to access the screw.
After screw is out the handle should come off you may have to wiggle it a little to get it to come loose. Next you will have access to the spring and washer for that stem.
It should be located on the bottom of the stem just remove it and replace new ones back in place.
Some have sping's and seat in the body of the faucet if not located on the bottom of the stem.

Hidden under the lever is a little hex screw. Use an appropriate hex a.k.a. "Allen" wrench to remove the handle. You might want to shut down the water service first to save your shower until later.

Hi,
Make sure the exact allen key is in the screw. take a small adjustable wrench, close it onto the allen key, and loose with wrench turning the allen key.
good luck

There are tabs in the cartridge and slots in the faucet body, line them up and push. If the handles turn incorrectly, turn the cartridge 180 degrees.
