Have a Delta model 155/6/7/8 ?? which is leaking at the spout swivel joint. Maybe need new o-rings (2) - RP37021 or bonnet washer - RP37022? need suggestion how to take spout apart...

Asked by: James
Thank you for your question, James304! To access the o-rings, first unscrew the bonnet counter-clockwise. It may help to use a flat rubber jar opener. You will then be able to lift up on the spout to remove it, pull off the spout retainer clip, and slide off the bonnet. Best regards, Jon

How do I replace O-ring 37021 on faucet model 186 & 187 downspout

Asked by: Hec
Hi Hec, Thank you for your question! To access the o-ring, grip the base of the faucet with one hand and turn the Spout Bonnet (RP40371) counter-clockwise with the other. Once it has been unscrewed from the spout base you can lift up on the spout, remove the spout retainer (RP21961) by pulling it apart first, and then slide off the bonnet. You can then remove and install the new o-rings. Thanks, Jon

How are the washers replaced?

Model156-WF How does one disassemble the faucet assembly to replace the two RP37021 washers?
Asked by: Gus Wolf
Hi Gus, Thank you for your question. You will need to grab the part of the spout assembly above the base of the spout and unscrew in a counter-clockwise direction. Once this entire piece is removed you should be able to unscrew the bonnet and release the top portion of the spout to change out the RP37021 o-rings. I have attached the parts breakdown for the model 156-WF to help with your repair. Thanks, Dave
