Determining water line in already installed Steam boiler
We have an account with a Utica 4 section oil fired steam boiler. The unit has been going through switches in the Mc Donnel Miller Low Water cut off. The water level seems to go above the normal operating level we think and is damaging the switch. We only can go by what the customer tells us. That said, the near boiler piping and Hartford loop are done in copper and done incorrectly. The Tee in the loop is too low and the eq tube is piped to a dry return from one steam main, instead of an elbow for the return at the HartfordLoop there is a Tee going op to the main as another Eq tube. The remainder of the return piping is original and I want to replace it as I believe it may have some restriction slowing the return water flow. We replaced the McDonnell water feeder with a hydrolevel feeder with time delay. This helped but then the switch failed. We would like to correct the return piping but would like to determine where the water line should be so that we could pipe a false water line or raise the boiler. Any ideas?
