Warranty on Parts*** We had recently replaced the shower cartridge for the existing delta monitor shower valve, we arrived today because client states a very minor drip is coming from the showerhead. When I went into the enclosure the shower head does have a very minor drip from it. I advised to the client to have me swap out the shower cartridge again to stop the dripping. I advised to the client, that if the drip does continue, replacement of the actual shower valve itself is highly recommended. I will leave a quote to replace the shower valve through tile, if needed, and will give some credit from the first visit towards the replacement.
