no suction when vacuuming to waste

Postby sydneyfnp » Thu 16 Aug, 2007 19:39

I have a major algae problem and know I need to vacuum to waste. Vacuum works fine when I hook it up while the sand filter is set to "filter" but once I change it to "waste" the suction disappears. Do I need to be re-routine something or turning something else on/off? Help!

Have you ever removed or disassembled your multi-port valve? Has the waste function worked correctly in the past? What, if anything, is attached to your waste port?

problems vacuuming to waste

Postby sydneyfnp » Thu 16 Aug, 2007 19:56

I have never taken any of it apart. We just moved into this house last fall, and have never owned a pool before. i know for certain this pool already has some issues - it was "parked" (filled in) in the past and the main drain is now full of cement and does not function. However, I also know the peple we bought the house from did manage to keep it looking just fine and used it a lot. I could ask the previous owner, but they only lived here a yr, so don't know if he ever had to use the "waste" function. -Sydney

On the valve itself there should be three ports. One labeled "Pump", one labeled "Waste" and one labeled "Return". Is anything connected to the "Waste" port like a blue backwash hose or is the port hard plumbed with PVC pipe? I am trying to determine if the problem is in the port or further down the line.

The reason I asked if you had removed it is that sometimes people take them apart to replace the spider gasket, and don't re-assemble them correctly, causing them to do very odd things like backwash into the pool, etc. :P

from what I can tell from reading your post your main drain which would send water to backwash area does not work, but can you backwash? If you can, then vacuum pool and then backwash until water looks clear unless you can not see it above ground then run 3 to 4 mins.

No extraneous attachments - just hard-plumbed w/ PVC pipe. -Sydney

I have the black lagoon out there, and from what I'm reading in order to get rid of that much guck you need to be bypassing the filter. I have vacuumed it the usual way (which does work) but when I do after only a few minutes the jet returning water into the pool begins shooting out all the crap I just vacuumed out. VERY frustrating! -Sydney

Mr. Clean, she has loads of gunk and would rather not clog her filter every five minutes...hence her request to vacuum to waste.

You do bring up a good point however...Sydney, are you able to backwash at all?

If so, this is very strange because the only difference between waste & Backwash is one goes through the filter backwards (bottom up) and one bypasses the filter altogether, but both use the waste port. If not, you have a clogged waste line or a valve somewhere that is closed.

The waste setting is one of the simplest on your valve because it simply redirects the water from the input port (pump) directly to the waste port with no restrictions and as a result should have MORE suction than any other setting!

I BELIEVE the backwash works. There are 2 different settings for backwash and waste. When I turn it to backwash I can see water movement through the trap where the basket sits to collect crud (there is no basket in the skimmer - the pool is very old - so it goes through this one next to the pump). Guess I haven't looked at the water flow in there with it set to waste. So it should look the same, eh?

Most importantly...where is that waste pipe going? (where is the other end?)

To a ditch? Storm drain? Back yard? Street?

I am curious to know if water is coming OUT of the waste pipe during backwash.
