A blocked water line causing water to loose heat?
*edit - this problem has been resolved, thanks for reading and responding*
I'll try to write this so it makes sense and doesn't confuse anyone - I need feedback before I start to fix the problem. sorry -I noticed I typed 'loose' instead of 'lose'
At the left side of the house is the laundry and kitchen, hot water heater.
Center is the master bathroom (the bathroom that I'm working on)
Right is the main bathroom (bathroom that I redid a few years ago).
The hot water line comes from the hot water heater - has 2 90 degree turns - and continues past the master bath and to the main bath like this:
Hot water heater ________ master bathroom ________ main bathroom
The other day I connect the master bath tub faucet into the hot water line. Connecting went mostly ok - no leaks (no leaks anywhere on the line, for that matter). When I installed the Tee onto the hot water line - which branches off to the new tub faucet - some water dribbled into the Tee from the right side. So I removed the Tee, wiped off the cement, let it dry, and re-cemented.
(I also connected the cold water line to the tub faucet - no problems happened).
However, since connecting the new line into the hot water supply line the hot water in the main bathroom (on the right side of the house) has only reached 90 degrees (I've checked it with a thermometer - at the sink and at the tub/shower)
COLD water flows fine and is quite cold in the main bathroom.
Hot water, however, just isn't as hot. . . it *seems* to have the same amount of water pressure, but it is just warm, not hot.
Hot water flows just fine through the kitchen sink and into the dishwasher and washing machine, too.
Now - I checked my lines SEVERAL times to ensure I didn't cross the lines over - hot is all hot, cold is all cold. There are NO leaks, I'm quite sure of this. I have checked the lines with the hot water running - being turned off and on, etc etc.
What I did notice, though, is that at the Tee where the new hot water line branches off and goes to the master-tub one side (the left side) of the Tee is hot to the touch (acceptable pipe hot - not too hot) and the other side of the Tee is much cooler (barely warm) to the touch - just 2 inches apart.
So - that leads me to question if the wet-cement inside the Tee expanded or somehow clogged the Tee and is slowing the flow of water. By the time the water runs through the blockage and up to the line it's lost 35 degrees (we have our water set at a temperature of 125).
This, to me, doesn't *quite* make sense. Wouldn't a blockage SLOW down the flow of water? (it's hard to tell - our faucet aerates the water, anyway, reduced pressure isn't obvious).
I've let the hot water run for 30 minutes - maybe thinking that it would eventually get 'hot' at that end - but that doesn't happen. It reaches 90 degrees and stays there.
So - if it's not a blockage of some type is it the distributor bar for the tub-faucet? Could it somehow be feeding cold water into the hot water line when the hot water is turned on?
But - that doesn't make any sense, either. I don't see HOW a faucet bar can fail like that and permit cold water to enter into a pressurized hot water line.
My plan is simple - replace the tee, be certain to dry the pipe well and not to over apply the cement - and see if it fixes the problem.
but if it doesn't? I guess I can cap off the lines to the tub and replace the distributor bar to see if it's defaulted somehow.
At this present moment in time I am making cabinets for the kitchen - just in case you wanted to know what I'm doing when I'm not around.
