    flo check replacement

    Unless it is at the highest point of the zone, you will have to isolate that zone and drain it in order to safely replace the unit without hurting yourself. You will then have to refill the loop and purge it. If you really don't know how to do this, it's a job for a pro. If you do it yourself, be careful. The water will be very hot and there is a lot electrical stuff around the boiler. Make sure to shut EVERYTHING electrical aroung the boier off before doing any work........again...this is a job for a pro.
