Question about Tetra 16361 Vacuum Bottom Drain Portable

1 Answer

Question before purchase (existing pond)

Wandering if I can get a 3" pipe connection. Also trying to visualize if the pipe (hopefully will accept 3" flex pvc) can connect to the "Tetra Vacuum Bottom Drain" and from there, run uphill above water level, over edging stones and back down to pond level (outside the pond) into a settling chamber, and then to a bio/mechanical combo filter U.V. etc., with the pump at the END of all of the above, not before. (I don't want dirty water churning through a pump first before it gets to filters, this method doesn't work) which then takes water to the waterfall and back into the pond. I cant visualize if it would work like that, coming up over edging rocks (ABOVE water level). Im wandering if I would have to cut a hole in the liner and use a bulkhead to keep the flex pvc below pond level the entire route described above. The answere is probably simple but I can't get it through my head how these things work. Thanks.

You don't need a bulkhead if your liner is EPDM. You can use a boot that is attached with adhesive that will seal you pvc piping. I don' t see a problem with dirty water going thru the pump before the filters. for some diagrams of settling tank installations see:

How do an intex pump to a non intex pool?

this question has come up before too me , what i respond with is it to be perminate or temporary ? , the reason i ask if its to be perminate then i suggest purchasing the correct filter for the pool, but on temporary situation (to just finish out season) then yes even though the pipe sizes are different , the use of std plumbing home DWV rubber soft connections available at any good hardware/homecenter would work , but heres the temporary part of it , saltwater pool water degrades the rubber making it brittle , but will last a month or so

I purchased a house that the pool filter was stolen and I purchased a used filter with a side mount valve. I need to know how to plumb itto my pool. there are 3 ports.

Thank you for posting your question here on

If it is a Hayward valve like your post suggests there will be a word cast into the black plastic area near all three ports you need to connect. One will say pump, another return and the last one waste.

Pipe the pump port to the pumps discharge. Pipe the return to a heater if one is present or back to the pool. Pipe the waste to an area where you can safely discharge water as you backwash the filter.

Marquis Hot Tub, Instrument Panels (Balboa Instruments main and side auxillary) do not display the LED read out. Replaced main control panel twice, replaced 250 W. 3/10 fuse.

The topside controls aren't fused so the fuses wont be the cause.

It can only be either the PCB, the topside controls, or a bad connection at fault. Check that they are plugged in correctly, make sure that the PCB is configured correctly for your topside controls.

It's rare for both the main and auxilary topside controls to fail. You can try plugging in another main topside control without fully installing it... at least you can then return it (ask whether or not return are accepted, I don't personally accept any returns if parts are specially ordered) if it doesn't cure the problem.

I have experienced this same problem and all I needed was to prime the pump. Unless your pump cannot pump up that high.

Aerate a pond

I live near Memphis TN so don't have that pesky "frozen water" problem. However, I do aerate my 2,500 gal goldfish pond with a Oase Biosys Skimmer (free standing/ floating skimmer) which is powered by a Laguna fountain pump. I attached a small pipe on the discharge end of the pump & set the pump so that this pipe is a few inches below the water's surface. The discharge provides a small fountain effect that keeps the surface moving while aerating the water. The skimmer keeps the leaves / debris off the top of the water the pump keeps the water moving...and moving water will not freeze. Hope this helps

Pump goes on and off

Does the pump have thermall protection? It sounds like its getting hot and tripping the thermal protection switch in the pump windings.
