Haywood Pump and DE Filter

[MissouriMule]

I have a 10 year old 1 HP Haywood pump and DE filter. After I made all the connections and added the dirt to start the year, I turned on the pump. It ran for about 5 minutes before I noticed the PSI was 20%. I immediately turned off motor and discovered I had not removed the return line plastic cover I use when closing the pool for the winter. After I removed the plastic cover the water comes out of the return very nicely. Do you think I caused any damage to the filter especially the cloth fingers? Waiting for your answer-thanks

No. You caught it in time.

Thanks for the reply--glad to know. Do you have an estimate as to the time it would take to cause serious trouble?

Damage to a filter from a pump running dry would be rare.
