  • how many diffusers should be installed with an HP80 pump?

    You can use one diffuser but it shortens the life of the septic air pump by a year to to years depending on what region of the United States you live in. In the southern part 2 years in the northern 1 year. It also depends on the diffuser a corse air bubble diffuser would have no effect on life time. The Clearstream diffusers are very restrictive and need changing yearly and we only recommend them in clearstream septic systems. The Hiblow diffuser is the the longest lasting poly bar type diffuser and normally can be cleared every 5 years using some muradic acid that can be bought at any hardware store.
