Water Temperature Sensor Location

[black_vanilla]

I am going to install the Hayward water temp sensor and want to make sure I put it in the optimal location. I read a few posts about it doesn’t matter and also read it was better to install it after pump but before filter. I added a picture and wanted to solicit some feedback on where ppl thought was the best place to install it.

I’ve installed mine right after the filter so it sees clean water and no debris wear it out.

Your SWCG is also incorrect. It should also be installed after the filter. The SWCG should be the very last thing in your system before the water exits the pool. Your SWCG gets unfiltered water running through it, which can’t be good at all; and your filter sees very high concentrations of chlorinated water constantly, which also can’t be good.

+1 above.

Your SWG should be installed after the filter for several reasons. It's consequential enough you'll want to move it. It needs to go where your sacrificial anode is.

You may need to go vertical in order to fit it, because the flow switch should be in the same run of pipe as the cell. Anode can go anywhere after being moved.

I went back and looked at the manual and you are correct. Thanks. Good news is I have time to fix it before it warms up…lol

+1. Sacrifice the anode and it will serve its stated purpose for once.

You may need to go vertical

If going vertical @black_vanilla , remember the flow switch needs 'upflow' so gravity on the down side can't close a failed switch.

I would leave the flow switch where it is because with simple plumbing, it can go anywhere. The key is that it needs to have flow when the SWG does, you don't have multiple legs which may be closed at times.

It is better to keep the flow switch horizontal if possible, so leaving be would be more ideal except we've seen the Tristar pumps rhythmically pulse when backpressure reached a certain level, from poorly maintained filters and deadheading. OP can't deadhead, so it just leaves filter impedence.

I'd feel better having it after the filter if it was mine.

Newby question here. What is the purpose of the ball valves and when would a person need to have one in their system?

 

[Newdude]

Valves close off a leg, or redirect flow in 2 of the 3 choices on a T, such as a heater bypass or when multiple skimmers/returns each have a leg back to the pad and you want to run one or the other.

ball valves are cheap by design and tend to break often. Rebuildable valves such as the Jandy Never Lube (or pentair / hayward evivalent) are preferred because you can easily replace the guts if ever need be. You also rarely need to with a beefier valve so it's a double win.

With the picture below, I don’t have a need for one do I?

Is your equipment pad above or below the water level?

Above

 

[ajw22]

With your equipment pad above the water level when you open your pump or filter for maintenance it should drain back into the pool.

If you had 3-way diverter valves at your suction and return T’s it would allow you to adjust the flow between the pipes, shutoff one pipe if it has a problem, and shutoff the equipment so it would not drain into the pool if opened for maintenance.

Your builder cheaped out not installing diverter valves at the T’s.

 

[ajw22]

Also, your SWG should be the last thing before the returns, after the filter, and not between the pump and filter.

That placement before the filter allows debris to get caught in the SWG cell and clog it. You want clean filtered water flowing through the SWG.

I see you were already told that in this thread…

It is best if you keep your questions about your equipment in one thread do we don’t cover old ground.
