Query: Too heavy for faucet

I bought this model Pur filter because it looked sturdier than the regular plastic faucet mounts Pur makes. But this particular mount is very heavy for an average kitchen faucet that it pulls the mechanism down too much. The slightest adjustment to the filter itself (even when you change the cartridge) can cause the threads of the filter to become stripped. Unless you have a real sturdy, high quality faucet, I wouldn't recommend this model. With that said, I probably wouldn't even chance it with an expensive kitchen unit for risk of damage to your kitchen faucet.
