Replacing my Hayward Northstar pump, filter, and re-plumbing

[mas985]

What's the chance that both skimmers tie in close to the one suction line right at my pool equipment? like i said a few posts ago, i plan to dig down and see if i can make them be on seperate lines to better control the suction of each skimmer.

More than likely if the PB connected the two skimmers close to the pool to save some pipe.

I have 4 jets, and when i measure the inside of the jet it is 1", the overall body size is 2 3/8". attached is a picture.
Based off of what I am reading my pump is not going to push enough water through that 2" pipe for all 4 of these jest.
should i reduce the size of the nozzel?

What you are showing there is the eyeball, not the nozzle. The spa jet nozzle is deep within the spa wall:

Nozzles are typically much less than a 1/2" in diameter. They look like this:

Bummer. the closest skimmer is about 12 feet from the pool equipment, and the skimmers are about 44 feet from each other. So the furthest skimmer is 56 feet away from the equipment pad. I'll dig a little bit and keep my fingers crossed.

Ill take a look tomorrow and see what I can find.
What size would I want for 4 jets with a 2" pipe?

 

[mas985]

2" pipe should be kept below 65 GPM but that is enough for 4x3/8" jets. 7/16" would required higher flow rates which should be possible but then would exceed the 6ft/sec recommendations for the plumbing.

Were the jets previously strong enough?

2" pipe should be kept below 65 GPM but that is enough for 4x3/8" jets assuming the pump can handle it with the filter head loss. 5/16" would also work but. 7/16" would required higher flow rates which should be possible but then would exceed the 6ft/sec recommendations for the plumbing.

Within the next few days ill be getting my new waterway crystal water 525 and Intelliflo3 hooked up. I would like to think it could, but we will see.

The pump i have now (2hp northstar) is not able to push the 4 jets. 3 would work good but not great and the 4th would sort of work.
Sounds like if i can maintiain a 65GPM then 3/8th's would be the way to go?

If you look at the 2 profile pictures attached it says the end closest to the thread is 5/16 and the end furthest from the thread is 7/16.
My assumption is i would go with the 5/16, correct?

I took this one off because it was the one not working, low and behold there was a bit of broken plastic that was clogging it. took it out and it's now pushing water through it but that old pump still can't push it like i think it should be able to.

You want to measure the orifice (i.e. I.D. hole) at the end of the nozzle opposite end of the thread. This should be the smallest opening. What you posted doesn't make sense. Can you post two pictures of the nozzle ends?

Ill go grab those pictures, but if your saying the I.D. hole furthest from the threads then that is 5/16's.

I measured the opposite end as good as possible and it is also 5/16's. not sure why the markings on the side of the nozel is saying 5/16's and 7/16's
Images attached.

I should have zoomed in on the other pictures. The 217-3360 is a 5/16" jet nozzle.

With the Intelliflo, cartridge filter and the heater inline with the jets, the operating point for the current jets should be about 52 GPM @84' of head. This is 13 GPM per jet which Waterways suggests is a strong jet so it should be sufficient. I would test this first before deciding on any new jets or drilling out the old jets. The new pump is stronger than the old pump so that might make a difference and the cartridge filter also has less head loss so that will help as well.

Also, I would recommend removing ALL the jet nozzles and running the pump to flush out the lines. Some of the nozzles might be getting clogged with debris.

Thanks Mas985 for all the info.

Once i get everything plumbed in, ill remove all the nozzles and let it clean out what ever might be in there.
Any other recommendations other than Jandy fittings? (Check Valves/3-way's)
My plan was to use Jandy fittings but dont have to if there are others i should look at.

 

[mas985]

Jandy Neverlube are a good choice.

Does anyone have any thoughts on hard 90’s vs. using sweep’s? I know they make a difference but I don’t think it is noticeable.

I found some sweeps at Grainger and ordered those. I always planned on using sweeps but it would make it easier to just use the hard 90’s.

 

[mas985]

Unless you have dozens on 90s it really won't make a difference. Other factors dominate.
