well... I do not have hot water going to my washer. never have had, never connected it as my better half washes EVERYTHING in cold water. as for the shower i have no idea what kind it is its in the wall on the other side of the tile, I can tell you only that thereis 2 supply lines running to it, one hot, one cold. this is how my layout is when talking about one being closer to the water heater than the other utillity room with water heater--- washer-----------------kitchen sink---------- Shower.
The shower being the farthest thing from the water heater, the washing machine the closest, with the kitchen sink about 3/4 of the way between the shower and water heater.
like i told you earlier, this morning Iflushed the water heater and it had only minimal effect. now, however, the water gets hot. i made no other changes in anything anywhere. this house is older, built in 1969. plumbing and wiring are two projects I'm going to have to face in the near future I think wiring will come first because it would upset me greatly to burn my house down right after I redid my plumbing.
I'd love to know what caused this problem, maybe it was the sediment in the tank. Thats the only thing I did. Thanks
