Pressure Booster on Hot Water
<span style="font-size:12pt">We recently added a third floor bath. While water pressure is not problematic anywhere else in the house, the missus is not happy with the (admittedly) meek hot water pressure in the shower. There’s a dedicated (recirculating) ¾” supply to the bath. At some point, we’d like to add a water softener to the hot water supply and I’m sure this will only exacerbate the problem. </span>

<span style="font-size:12pt">I know that too high a water pressure can cause problems with wear and tear on appliances, etc. Is it feasible to add a booster pump to only the ¾” hot line serving the third floor bath? Any of the pumps I’ve looked at really seem to be “whole house” solutions- would that kind of overkill be ok assuming the pressure setting could be dialed back appropriately? Is there a better (smaller?) option for this kind of application?</span>
<span style="font-size:12pt"> It also looks like these types of pumps are not rated for hot water. If it is necessary to place the pump before the water heater, I’m imagining I’ll end up with more pressure than I need on the first floor to approach desired pressure on the third. Any thoughts on this? Worried about nothing?</span>
