So when it rains it pours... While dealing with the MH ballast issue we noticed that the pump that feeds the UV Sterilizer and the carbon reactors has died. I am not sure what is wrong with the pump, but when I took it apart, I broke the impeller shaft, so that is another issue. We have another pump to replace it, so the UV unit is the problem. The pump was not pushing water to it, so I think the UV unit itself was on with out any water left in it.

We only noticed it because we were replacing the UV bulb. The UV unit does not appear to work any longer, as we tried it with both the new and old bulb and neither work.

If it was running dry, would it just burn out the bulb or would it burn up the whole unit? Anyone have any experience with this?

Thanks, Mike
