With all the features and the fact this is a new pool, I would go with a VS pump. That will give you the most flexibility to adjust flow rates and optimize energy use. But I would not under any circumstances get a cleaner that requires a booster pump. There is absolutely no need for that. ThePoolCleaner is a very good cleaner that doesn't require a booster and uses less flow rate than any other cleaner on the market. Also, there should be no problem running everything with a single pump and the proper pipe and valving.Flamingo Bay said:3. The pool is going to be about 38K gallon. What hp should a main pump (VS) be proper for this size without overdoing it?
4. I won't have a spa. The only water features are going to be 5 deck jets. Again the two top candidates deal with this differently. One was going to use a 1.5hp booster pump to run the deck jets. The other was going to use an actuator valve. Pros and Cons of each?
5. One PB wants to put in another booster pump to run a Pentair Legend cleaner. Is it really necessary? I thought the purpose of the VS is to run at different speeds to accommodate the different functionality (water feature vs. cleaner vs. water circulation). What's the point of having a VS pump and still have two other booster pumps?
7. Honestly I have no idea since we never had a pool before. I just know we'll probalby want to see the water jets on when we out there swimming or spending the outdoor time - that'll mostly be in the afternoon to evening. So when do the other two functions need to be on usually and for how long? Could I at least drop one pump safely/conveniently? I'm imagining a cost different between a booster pump vs. actuator - can't tell from the bid since one is not itemized.
It is true that a heat bended pipe will have less head loss, if done properly, but I wouldn't base any decision on who to go with just on that. Like most things, it depends on a competent installer.Flamingo Bay said:8. Heat bend or not - there are a few builders including some large ones everyone knows use heat treated PVC pipes. They touted as a way to improve hydraulic flow. Well, of course the others talked down on it, saying that's where a lot of the leaks happened. Just by common sense, I feel that it's gonna be your weakest spot on the pipe and you are trying to get a product do what it's not suppose to do - I mean that's why fittings exist, right? But the ones using it are giving lifetime warranty on their plumbing. What do you guys think?
So out of the four bids we are looking at right now, three of PBs were going with 3 pumps with the main pump being VS anyway. The one that proposes one pump would have Pentair Intelliflo SVRS PUMP (VS + SVRS 3/4 HP - 3 HP) with Jandy never lube 2” X 2 1/2” three way valves. Is this one PB providing a sound solution?mas985 said:there should be no problem running everything with a single pump and the proper pipe and valving.
Flamingo Bay said:So now I'm trying to compare the strength of the pool shell. I have a couple of builders do 10-12" wall/floor, 14" in transition with 1/2 " steel at 10"x10" and 10" x 5" at stress point. Then the other PB does 9" wall/floor and 12" cove with #3 rebar at 8" x 8" in walls and 8" x 4" in cove and floor.
Could anybody comment on the comparison between the two? Which one would be a stronger shell or they are about same?
