Hi, I have an Eco Smart 37KW inline water heater and I'm experiencing low hot water pressure only at the bathrooms shower heads. Cold water pressure probably comes out double to that of the hot pressure. I know this because I took off the shower heads. The kitchen faucet water pressure is equal on hot and cold and gets hotter than in the shower (it actually burns your hand. In the shower it doesn't get that hot). I opened up the water heater to have the heating elements cleaned and expected to find some type of calcium buildup or scaling but this wasn't the case. Only one of the elements had deposits but not something to worry about. I was also expecting buildup at the outlet restrictor of the water heater but that was also fine. Both of my bathrooms have individual valves for hot and cold. I took apart the hot water valve to see if there was a blockage but I didn't see anything. There is definitely a blockage somewhere but I don't know what else to do. Now that I'm thinking about it... I don't remember if I let the water run long enough after I took apart the valve to have any debris run out. I did this 3months ago, that's why I cant remember. My water pressure has decreased a bit more and I can shower by only opening the hot water valve (no need for cold like in the past). Any suggestions is appreciated. Thanks
