I just installed a Jacuzzi whirlpool tub. To help fill it, I would like to install a tempering valve at the hot water heater and raise the temperature of the WH.
Right now the water is set around 130 degrees. By using the tempering valve, I can use the existing (40 gal) WH that is only 4 yrs old. Whomever installed the WH (we just bought the house a few years ago) necked down from 3/4" to 1/2" copper right at the WH inlet and outlet. All the lines in the house are 1/2" only.
My question: If I buy the Watts 70A tempering valve, which has 1/2" connections, will this noticeably impede the flow? Or should I buy the 3/4" connection model and plumb it in. I'm not sure how much flow restriction the 1/2" model will have. There has to be enough flow to fill the tub in a reasonable amount of time. Right now, without a tempering valve, it fills fairly quickly.
Thanks
