Waterpump brass impeller replaces plastic

For those who seek to replace their water pump's damaged impellers, try using the brass kind instead if the plastic one. Sure its heavier but when submerged underwater, its weight evens out. Performance is still the same. When you change the impeller though, we recommend that you change the guide vane for a worry free waterpump. Most impeller/guidevane problems are caused by defective bearings, replace them from time to time.
