Pegasus Contemporary Series Home Depot
#856 0111 BN

46700The handle is leaking - I have tightened the base down as tight as I can and the water comes up through the top (left on picture) and is leaking out of the handle. Any suggestions? The leak is really slow - almost not noticeable, but does build up and spill over the top. Thanks

The leak is from the cartridge inside the handle. Remove the handle and try removing the cover from the base. It probably unscrews from the base. If you have difficulty, go to Home Depot and see if you can find the same model and look at assembly instructions. Also get model number of faucet, name doesn't help much when searching for parts.
Once you have removed the cover of the handle you should be able to remove and replace the cartridge. You should be able to find a replacement cartridge at Home depot or on line.

Does anyone know the correct model number for this Pegasus? Some told me that it was Pegasus Contemporary Series Home Depot
#856 0111 BN, but I cannot find it anywhere on the internet.

Mine is a bronze similar to #891-0131 - someone please help. Thanks
