You bet. When the tap water gets above 70 degrees an immersion cooler struggles. I took a friends immersion cooler (25' of 3/8) and put it in a 5 gal plastic pail. I connected the water inlet from the sink to this cooler and ran a hose from it's output to my normal chiller.
I use I just run tap water through the two chillers until I'm below a 100 degrees then I add ice and water to the 5 gal pail. The ice water chills the incoming water to the wort chiller and the next 30 degrees goes quickly. Takes about two bags of ice to do the deed.
