I'm new to this forum, and could use a little help from all you pool experts out there
Long story short basically what we would like to know is if our DE filter backwash is connected to the sewer line, or if we need to connect a backwash hose and where?
We just bought a house with a green muddy pool aka swamp, and as first time home owners and first time pool owners as well we have been spending a lot of time reading up on what to do about it in the last couple of days, shopping for chemicals and tools, so far we just started with a bit of psysical cleanup with a leaf net and cleaned the skimmer, and have been able to get some nasty green algies and leaves out of the pool.
Our first problem is we don't know a lot about how the plumbing is done on this pool, and before adding chlorine & other chemicals we'd like to backwash the DE Filter, to get some of the algie guck out of there. When running the DE Filter pump yesterday after a while the pressure gauge was showing pretty high numbers around 1.8 kg / cm2 = 25.6 PSI, so it seems it's needed also...
From the guides on how to backwash a DE Filter most say you should connect a hose to the backwash valve, but when looking around the pool equipment area, we can't see a backwash hose or anywhere to connect one for that matter, so we haven't dared to do it yet. When trying to find info about this it seems some pools are directly connected to the sewer pipe, but I don't know what to look for.
I've included some pics of the plumbing in the pool equipment area, if it's possible to see from there if our setup has backwash connected to the sewer line, or if we need to connect a backwash hose?
We did some tests with the test kit from walmart yesterday night, so we know that chlorine level was not measurable so basically 0, pH is way too high (purple) so is above the 8.2 color grade in the test, and cya level is also probably close to 0 (the tube was completely clear filled to the top, with the test tube range starting at 30), TA seems to be fine at 90-100 and calcium also seems fine at around 270-280.
The plan is to shock the pool to kill the algies, and get the water cleared up, by the steps in the following order:
1, first cleaning out as much of the algies and leaves as we can (since we can't see to the bottom it's hard to know exactly how much and where all of it is)
2, backwash the DE filter
3, shock pool by adding dichlor/trichlor which seems good in this case to get chlorine levels up, cya levels up and pH levels down
4, then when we have the water reasonably clean do a service on the DE filter with a full cleanup & change any grids that might need changing
