I'm new to TFP And pool ownership (recently bought a home with an in-ground pool) and I have already found these forums SO helpful!
We've been doing a good job backwashing and rinsing (about once per week) but when I backwashed today I saw that water and sand were literally GUSHING out of the drain pipe (buried pipe drains out to the street) when on the 'backwash' setting. Its like it thinks it is on the 'waste' or 'rinse' setting instead of the backwash setting!
From reading on this forum a bit I think it may be due to the 'spider' valve but I wanted to see if anyone thought it could possibly be anything else before I went ahead and bought a new one. (This is our replacement part: Hayward SP0714T, http://www.amazon.com/Hayward-SP0714T-V ... B00269II66)
Thank you in advance!
