I didn't buy this faucet, as it was installed when I bought the house. The sprayer hose was leaking, and I couldn't find any replacement hoses locally (tried 5 different local hardware stores). I ended up contacting support, and they sent me a replacement hose after sending them pictures of the connector ends.

Shipping was a little expensive (since I'm in Canada), but they didn't charge me for the part - which I appreciate - especially considering I don't have any original receipts.
