Hot Water Gone After Water Filter Replacement

It sounds like you loosened some sediment in the lines when you shut off the water and it has plugged up something in the system when you turned everything back on. Check your faucet aerators and if you have a tankless in your boiler, you may have sediment in the flow restrictor or in the tempering valve. I had the same problem over the weekend. We drained and removed a small undercounter water heater and reinstalled it the next day. There was enough sediment to plug up the new braided flex connectors we installed to the new sink....stuff happens

Hot Water Gone After Water Filter Replacement

Hi All,

I just replaced the filter in my whole-house water filter system since we moved in back in September. The old filter was a pretty horrific sight (loads of sediment from well water), but I was able to toss in a new filter no problem.

However, since I've turned the main water shutoff back on, I've been having some very strange issues. For one, there is no hot water to be had from any faucet. Cold water flows fine - for the most part (and seems to be improved over the flow prior to replacing the filter). However, the cold water from our kitchen sink is not coming out - not sure why this would be different than the other cold water supplies that appear to be working great.

The water boiler (oil fired) seems to be uncooperative, and does not want to turn on any more. Could there have been something that I did while replacing the filter that would have caused this? The temperature reading on the boiler is about 225 degrees Farenheit, which, if I didn't know any better, would think is extremely high. However, I never really monitored the temperature before, so I'm not sure how this compares.

Thanks in advance for any advice!
