Valve ID please.

Hey all. Bought a house and I have all the equipment figured out but one valve. What could the valve a few inches where the water comes out the filter?

Welcome to the forum!
Are you speaking about the hose bib? That was used by the installer to pressure test, etc. It has little function at this point. Some will say to use it if you need to drain some water. But in Phoenix, the only time you will need to drain any water is due to sky high CH or CYA, and then you need to drain the entire pool volume. And you will need a sump pump to do that.
I suggest you read ABC's of Pool Water Chemistry.

22,

Are you talking about the hose bib?? If so, it is not needed, but it could be used to drain water when the pump is running.

It is not normally in that location. Usually, just after the pump...

Thanks,

Jim R.

Thanks for the replies. Not the hose bib. The black valve in the bottom pvc going into ground connected to the filter. Think it diverts to sewer? Hope I explained ok. If not I'll edit pic and circle

 

[Bragz22]

Zoomed in. The valve in the center.

 

[mknauss]

Ah.
Not sure. How you have it set in that picture the water is going to the pipe going into the ground.
That is not a normal plumbing set up for a cartridge filter, which I assume is what you have.

 

[Bragz22]

To be honest it's been in that position since we bought the house. Just didn't want to move until I knew what it did.

 

[mknauss]

Then the water is going back to the pool. Where does the line going to the right from that valve go to?

 

[Bragz22]

Looks like to the valve that diverts to spa or pool and ground. Here's a different angle. There's just alot going on here.

 

[mknauss]

The valve is set so no flow to the right. So the pipe that goes underground carries the water. So it from there ends up in the pool returns.

 

[Bragz22]

Thanks for all the info. Gives me an idea of what to do.

It's a heater bypass.

As it is set, the heater is receiving flow.

To bypass the heater, you would rotate the valve 90 degrees clockwise.

This will block flow to the heater.

Note that the heater pressure switch will still be activated and the heater can run with no flow.

So, the heater has to be completely off and unpowered when the bypass is open.

Do you have a picture of the pipes going into and out of the heater?

Do you have pictures of the whole system from several angles?

 

[Bragz22]

That makes sense. Here are some more pics. Had a pool before. Just never a heater or uv or o2. This even had it's own pump just for the water feature. Just way more than my previous.

 

[Bragz22]

Guess next question would be what's position should it be in when not in use? I assume water going through is fine but would no water for a long period be bad? Again thanks for all the info. This forum is awesome and hopefully I can give back at some point.

 

[JamesW]

If you rotate the valve handle 90 degrees counterclockwise, the gate (where it says “Off”) will be at the top and the heater and the bypass will both be open or you can rotate the handle 90 degrees clockwise and the heater line will be closed.

Either way, the heater needs to be off and unpowered or it might run and damage the heater.

Do you have a picture of the plumbing going to the heater?

Maybe just angle of the picture but I see no pipes coming and going from heater.

 

[Bragz22]

Here ya go.

 

[JamesW]

Note that the heater has a bond lug with no bond wire.

Any equipment that comes with a bond lug should receive a bond wire.

Here ya go.
