Questions for the gurus out there:

I recently bought a 17 year old house in the DFW area and it has propane appliances. There is an electric recirculator that is operated by buttons at all the faucets and is on a timer. The house has Delta Monitor faucets throughout the house and I have had to replace many sink faucets for leaks. The showers have the "Delta MultiChoice" rough valve bodies.

The shower temp in the guest bath tub/shower always ran warm only, 95 degrees, and two feet away in the sink, the hot water temp is 125. If I turn the cold on in the sink, the temp rises to 102. If I turn the hot water on in the sink, the temp drops to 90 degrees...???

The half-bath sink which is farthest from the hot water tank is 125.

The kitchen sink in the middle of the house runs 100. If I run the water in the guest bath, (and probably any other bath), the temp rises to 125.

In the master bathroom, there is the shower with 2 separate valves and shower heads, a bathtub, and 2 sinks.

The sink farthest away gets to 125 degrees.

The bathtub gets to 125.

The sink next to the bathtub and the shower never gets above 75.

The shower, both heads will reach 105.

If I open the cold on the closest sink, no change.

If I open the hot on the closest sink, both shower heads get up to 125....?

The 50 gal Propane water heater went out, so I just installed a new one, no difference. If anything, the master got a few degrees cooler...

The antiscald setting in the handles is already set to the hottest setting, and so i went ahead and replaced the valve cartridges in both shower faucets, still no change.

Next, I am going to try unplugging the recirculator.

Please help. Thank you in advance!

SOLVED! I found a valve on the recirc, shut it and unplugged it, and Shazam! Now have 120 at both showers, and the sink in the master that never got hotter than 72!

You probably need to fix the check valve and restart the circulator as you now have at least one dead leg full of warm water that will breed bacteria in your water piping.

Hey, wait a minute.

This is awkward, but...
