color:#1F497D">For our residential SHW installs a savvy client recently
approached us on the difference between mixing valves and anti-scald valves to
temper the hot water out of our tank. After doing a little research it appears
that the majority of our suppliers are simply using valves that meet the ASSE
1017 standard which is technically not supposed to be used for delivery water.
Here are some notes:</span></p>

<p class="MsoNormal">Note that the following says ASSE 1017 devices should not be
used to deliver hot water to the user.</p>

<p class="MsoNormal">A Word about American Society of Sanitary Engineering (ASSE)
Standards 1016, 1017 and 1070</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">ASSE 1016 covers the delivery of water at the individual
fixtures that are adjusted and controlled by the user. Therefore, it addresses
very precise and immediate temperature regulation requirements. This standard
covers three types of valves: Pressure Balancing, Thermostatic and Combined
Pressure Balancing/Thermostatic. Watts ASSE 1016 listed valves meet the thermostatic
requirements of this standard.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">ASSE 1070 is a recently approved standard and the newest of
the three standards. It covers control of maximum temperature to a fixture or
group of fixtures; such as sinks, lavatories or bathtubs. The device may either
be the final temperature regulation or have water further tempered downstream
with the addition of cold water.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">ASSE 1017, on the other hand, does not address final
temperature control at fixtures and appliances. It is concerned with valves
used at the source of hot water for distribution to the supply system, and
therefore allows wider variation of the outlet temperature at higher flow
rates.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">ASSE 1017 listed devices should never be used to deliver
water directly to the user. These valves should be used in combination with an
ASSE 1016 and/or ASSE 1070 listed devices.</p>

the info above that we need to use valves that meet the ASSE 1017 standard but
maybe I'm over thinking it?</span></p>
