For this customer, they wanted the two water heaters flushed out that the way that they were piped in. It was in series so therefore, I only had to drain one tank for the other tank to drain as well drained out both tanks. The reason for the call was a factor of hot water, not reaching the highest level, and that is subject due to the fact that the recirculation pump is bad and I recommend replacing the recirculation pump and the check valve as a result the customer has declined for now and just wanted the two tanks flushed at this time. Both tanks have been flushed. There are a video of it being flushed and the weight of the tanks have lessened at this time. There are no leaks turned off the two water heaters prior to doing the flushing. Let the water heat up to about 100° in the customer should be good in about 30 minutes.
