We have a new pool with spa (7 jets). We originally had a silencer producing bubbles only when water is cold; it would shut off after 1min when temp >100F. Pool guy replaced silencer with different blower (Polaris). Same issue, although the blower now stays on when water is hot, but still no bubbles (is producing bubbles also when water is cold - and does not shut off either).
Both blowers have worked initially when installed once or twice for 5-10min when temp>100F. After that we see the symptoms as described above.
Any ideas? Thank you so much.
