Can an over-sized pump cause my Game Solar Pro heater to fail?

How are you figuring that the solar's not working?
If the water moves through the solar collector faster, it won't get as warm but it will move more heat into the pool.

Thanks for the replies. The solar heater is one of those rigid plastic dome - shaped models so I don't think the fast water would be able to harm the tubing.

The temp in the pool is not going up. I remember last year (using the pathetic pump that comes with these pools), the incoming water was HOT. This year, it feels the same as the pool water. I have it in full sun.

That would be expected, if you had much fast flow rates.

But in terms of total heat added to your pool, the end result from 2 gpm at 15 degrees hotter than the pool, is the same is 20gpm at 1.5 degrees hotter than the pool.
