If the spa level drops overnight, it may indicate a failing check valve.  Once the circulation system starts up again in the morning, the spa refills and overflows into the pool. This is a common problem with a simple solution - replace the check valve. Location: normally on the bypass loop at the pool return line.  It takes some skill to replumb a new valve here, so you may need to hire a professional.  In Woodland Hills, Burbank or Pacific Palisades, pool repair technicians are readily available to resolve issues like this.  We at Spectrum take pride in our years of in-field experience. Our goal is to seek the ideal solution; large or small, we seek the correct way to repair an ailing system.
