Well..... It’s me again. The owner/builder with a screw up at every turn. This time it's in the plumbing. I got water going last Thursday; finally got power to the pump on Monday. My water does not look right. I have a dark grey plaster and instead of dark blue water it is greyish greenish. Looks like lake water. I don't know if it's in the plaster job (have concerns about that as well, but holding my breath)...... or the filtration; however I have found a mess up in the filter plumbing. I have the Pentair TR100 with the push-pull valve. When my husband and I were doing the initial start up of the filter we noticed that the up and down positions were opposite from what the directions were saying. The filter position was in the down position (instead of the up position) and the backwash position was in the up position (instead of the down) We were able to get it going, be we had to do the ups and downs opposite.
I have finally figured out that the side valve is plumbed for the DE filter not the sand filter. The top and bottom lines are reversed. It should be top pipe to backwash, middle from pump to filter, and bottom from filter to pool. Instead the top goes from filter to pool; the middle is the same (from pump to filter) and the bottom from filter to waste. My question is..... As long as I know they are reversed and move the handle in the opposite directions for filter and backwash, will it work properly; or does it have to be re-plumbed to the correct configuration. I think I can switch the two that are backward without too much difficulty, but don't want to if I don't have to. I would like to fix this myself if possible. I would appreciate any advice.
