I've got a 5000-2 valve on my dhw to mix my 150° down to 125. I installed it new about 3 months ago and has been mixing well until this week. This week the chilly showers began. I've since had to keep adjusting the temp up to keep dhw supply temps up. I also starts out with a 30 sec or so flow of excessively hot water.
It's installed per the supplied instructions. Any thoughts?
