Deep in the heart of Southern California, there resides a castle. At the LEGOLAND® Castle Hotel at LEGOLAND California Resort, 250 deluxe LEGO Castle rooms with themes like Knights & Dragons, Royal Princess or Magic Wizard host many visitors from far-off lands, and CircuitSolver® had a hand in delighting children of all ages.

At this magical 3-story hotel in Carlsbad, California, Ed Parisi, Plumbing Design Manager at ICS (Industrial Commercial Systems) installed CircuitSolver®s in this construction project. “At ICS, CircuitSolver® is our standard balancing valve for all projects,” Parisi notes.
The 250-room hotel is a U-shaped building and required exactly 99 3/4″ CSUA CircuitSolver®s. ICS ordered these through Todd Pipe (now Reece) in San Diego.
“This is a typical installation with the CircuitSolver®s installed at the end of each DHW branch before it ties into the circulating main,” Parisi says. “In this project, the furthest CircuitSolver® was approximately 650 feet of piping away from the Mechanical Room.”
In the LEGOLAND® Castle Hotel, the domestic hot water mains followed the 1st floor corridor through the building and the branches served two or three-story stacks of rooms throughout the building.
“Time to tap, I have never seen a building so consistently deliver hot water that fast!” Parisi explains. “I’m impressed with the whole system.”
“Ordering the assembled CircuitSolver®s allowed ICS to use less jobsite manpower and also enabled us to install every balancing valve correctly. There were no leaks, and I never had a callback during the warranty period. Nothing but hot water!” he says. “It’s a pleasure to use.”

“ICS used a Grundfos Magna3 circulator pump with an ECM motor set for proportional pressure control. This pump used with the CircuitSolver®s provided an extremely efficient circulation system. The commissioning agent complimented the Domestic Hot Water System saying that he had never experienced a system with such consistently low “time to tap” readings. The owner’s maintenance supervisor also complimented the system,” Parisi explains.
The LEGOLAND® Castle Hotel project was completed in April of 2018 and was open to the public that same month.
Parisi was introduced to CircuitSolver® in 2012 by Chrissy Hamm from Specification Sales in Ontario, CA. “Chrissy guided me through my first couple of orders and I have only ordered CircuitSolver®s since then.
“CircuitSolver®s are the premier balancing valves available. Reliable, stainless-steel construction, variable temperature settings available, and all the necessary components to satisfy the most stringent specifications and details. All that plus no manual setting required makes CircuitSolver®s a great solution,” he says.
