Adding a Pump

Hello all. I have a large 30k pool and a hot tub. Currently everything runs through one Hayward variable speed pump. I'm trying to plan a major upgrade.

items I'm sure on:
1.) I'm going to add automation
2.) in order to support #1 I'm going to replace the all the valves with Jandy 4715 valves so I can add actuators (Thinking Intermatic Pe24VA).
3.) I'm going to add two water features. A rather large Waterfall and 2 Fire Bowls

What I'm not sure on and my reason or coming here:
I'm looking to add a second pump so I can have one pump operating the hot tub and the existing pump to continue operating the pool / water features. Additionally, when we have guests I would like the hot tub to run and heat from the heatpump, and the water features to operate.

Logistically I'm not sure where to add the second pump in the current setup and what to draw / feed the two pumps out to. I would like to avoid adding a second filter if possible due to the additional cleaning requirement.
To complicate things more, there is 1 Large heat pump that I would like to be able to switch back and forth between the hot tub and pool as I do now. Right now, it keeps the pool at temperature and when we want to use the hot tub, I rotate the valves so the pump is dedicated to the hot tub for heating.

Please see the attached photos of the current system. The current filter is a Pentair DE Filter and the current Pump is a Hayward SP3400VSPVR 2.7 HP Variable speed pump.

Any help or additional ideas is MUCH Appreciated.

Can you clarify the intake, I can’t read the labels. Where does the pipe that goes up the wall lead to? Blower? The pipes running to the far right lead to HP and one is waste? I personally have had issues with the intermatic actuators, they break down quite frequently.
 
From the top picture:

Pipe that goes up the wall is to a blower. Correct.

The pipes on the far right are heat pump in and out. (The closest is the return from the heat pump that goes to the salt cell then to the return valves.

The far right against the wall is waste.

The intakes on the left of the pump are skimmer / vac.

The intakes on the right of the pump are pool main and spa main.
 
I believe you will have to have separate suction lines for each pump.
On the pool side, is there a separate suction line from the main drain and another from the skimmer?

You can add actuators to those existing valves.the adtuators don't need to be Jandy brand.

If you add automation, be sure that the brand matches that of the pumps and SWG. You really can't mix and match in this respect.
 
Yes the SWG and Pump are both Hayward. I obviously plan on sticking with that brand for the automation. (A topic for another thread, I want to try to focus on the plumbing here)
Those valves are 30+ year old Jandy valves and EXTREMELY hard to move by hand. They need to get replaced. I'm trying to plan the system now so I don't have to do anything twice.

Poolbreh, what brand actuator do u recommend?

attached is the system layout picture labeled.

Obviously, each pump needs a suction line, hence the main reason for my post. What suctions to put on 1 pump vs the other. Also I'm hoping there can be a valve to connect the two systems so 1 pump can run the entire system / heat pump / filter when its not actively being used. (ie. Winter time.) I have seen a setup that has had everything on my wish list, I wish I took a picture. I don't know how it was done.

I would try and clean up the piping off the pad, I would move the blower vertical instead of horizontal than vertical. I would divert HP plumbing outside of pad than run to HP just to clear room. Move the filter to the right, and water feature pump between FP and filter. Your WF intake would be main drain(separate from FP)as long as they are safe. What would be your 4 actuators? Intake, return, jets,(bubbler,wf)? Or does bubbler and wf run at the same time? Are you running WF return above ground?
 
I would do something like this. I like jandy Pentair, gold line. Most automations come with 2 as a bundle. So it depends on your automation.

The bubbler is a very large bubbler and bolted to the wall. I’m a little confused because the bubbler pipe goes into the ground and what happens after that is a mystery.

The heat pump is a good 10-15 feet away and the plumbing on the right (in the labeled picture) runs underground to the heat pump which is out of the way.

Based on the bubbler info I’m a little confused because no line connects from the pump (that I can see).

Sorry I wrote bubblers instead of firebowls. Are the firebowls going to be included in the water feature? If not just run WF pump to waterfall. The blower isn’t included in the diagram. I would just move it vertically up right where it’s coming out of the ground (same height) so it’s not taking up prime real estate on your pad. But if you can make it all fit no need to move. The HP in diagram is just for reference. I would replumb pipe so it’s not in the way if you want to move the filter to the right.
