Good morning guys! Let the season begin!!
I've come home twice this week and have had barely any water flow out of the return. Pump was running, sounded normal. Pressure was around 17. It is usually at 11. I backwashed after vacuuming last weekend. So I didn't think it was that. On both occassions I turned off the pump and then turned it back on and the flow returned. I woke up this morning and it was pushing slow again. I did another backwash, rinse and now the water is pushing fine. Any idea what's going on and what I can look for?
Also, when is one "supposed" to change their sand? The current sand is 4 years old.
