Hi, I have a leak in my sprayer hose and the plumbing company (reputable) who came out to look at it could not figure out the model. The sink is made by Suneli, which appears at some point to have been purchased by ZOJE. The diverter is completely opposite anything the plumber has seen and his recommendation is to replace the entire faucet and spray at a cost of close to $1000. Has anyone encountered a similar problem or have any experience with Suneli/ZOJE products. Thanks in advance for any assistance.
