I had this water heater installed many years ago to replace the old unit that was leaking. I think the install was done by Lowes. It was originally over just plain wooden boards with no extra support directly under the heater. After a leak, we put some vinyl sheet in to prevent water from ruining the wood and had reinforcements put under the wood to hold it up because it was sagging. Later when my air conditioner was replaced, the HVAC man told me that the heater wasn't installed correctly, but he didn't say what was wrong and when I asked him to elaborate, he got distracted by one of his workers and never told me. Anyway, after a recent problem with my water well system, the hot water pressure has been unstable. Not only is the water coming out very cloudy and full of sediment, but it spurts. It will stop flow for a split second and then spurt very hard. Sometimes the flow will be fine and then there is a hard spurt. I'll be washing dishes and suddenly the water will blast so hard it slams the dish out of my hands and splashes water all over me. It does not seem to be an issue with the cold water from the same faucet (the only cold water spot that seems to have an issue is the toilet water supply-- but I wonder if that could be the fill valve needing to be cleaned again). I was reading instructions on how to flush an electric hot water heater and it said to shut off the cold water supply at the top of the top of the heater-- but there is no shutoff. Is that normal or should there be one there? Also, the heater sits so low on the platform that they had to turn the drain faucet at an angle to be able to fit a hose on. Is this a problem? Does this look installed correctly? There is no floor drain so I would have to either fill buckets or run the hose around a few corners to drain into the bathtub. Any tips/suggestions? (aside from dusting and cleaning it up?). I know I will have to turn the heater off a few hours prior to draining it (so the water can cool). I didn't see an off switch, so I can turn it off at the breaker.
