Hi Alan, The best thing you could do is every 3-5 years replace your DMJ-172 Shaft Seal this shown as key #10 in the Sta-Rite DMJ-172 Exploded Parts Breakdown.

What is the difference between a high head or medium head pump? My data plate is missing and I do not know what I have.

Hi Douglas, High head pump are design to push less water higher using more pressure verses medium head pumps are designed to push more water using less pressure so the water flow will not be pushed as high. If you can get us the impeller info we can find out which pump you have.
