Domestic pool turnover rates

[Anonymous [GDPR] European in the UK]

Thank you Richard,
Yes whilst I do run 24/7 it's due to having lots of trees around, not everyone will, but some who post on the forum do so different ways of running for given situations. I am not saying everyone has to run 24 hours and if you are willing to accept less, fine but has anyone explored what happens if you do run 24 hours, no because of the cost. My cost are low, very low, It cost me less to run 24 hours than most other pools cost for 2 hours. That's where the study has been going on.

Just like Mark's study on turnover it appears we need a lot less turnover than previously thought. If I had less trees I would almost certainly reduce the run time but as I said you can only skim the surface if the equipment is running.

Yes I appreciate what can and cannot be filtered but even biofilms break free and normal filtration doesn't catch them it circulates them.

There is as you point out a point at which the water flow is insufficient to achieve a skimming action and so there is a flow at which we can't go any lower in my pool that appears to be 23GPM. Being an oval pool it's more hydrodynamic than a rectangle and you hit the spot with the return jets. Too many lazy pool builders do not know or plan the placement of skimmers or returns or even the number of returns. I was able to sell my robot as running as I do it wasn't needed even with the number of trees I have but I have to empty the skimmers more frequently because that's where it all ends up and on low energy pumping the flow can drop and the automatic sensor will cut off the pump if water stops flowing to protect the pump. As you said pool equipment was never made with efficiency in mind.

Your pool looks good Richard but there is extra electricity being used for the booster pump for the pressure side cleaner, I just use a Pool Blaster max now days although I can of course use the old vacuum head and hose should anything happen but it hasn't and less work is required now to look after the pool.

Just sharing what I have spent my time doing, and the turnover thing for domestic pools is a red herring but better to have a finer filtration and collect stuff which works even better on slow filtration than fast. We are all energy savers but single speed pump pool owners may hopefully gain something.

Regards to all on the Pool Forum in case Carl doesn't like what I have written and issues a 3rd warning.

Ben is not here to make judgements or correct errors I may make as a moderator. There are only myself and WaterMom. We have to make decisions about appropriate posts ourself, without Ben.

If you have an understanding with Ben, that's fine, but your posts made it sound like you are a pro in the business--and we have definite rules about that. As I said, if you are not a pro, those rules don't apply.

I'm not sure I have access to your eMail--Ben keeps many powers to himself as is his right--and private messaging is shut down. But I do have other powers to ensure our rules are followed and decorum is maintained. I'd prefer not to use them, and rarely have over the years.

Understood Carl, Please point me to your rules for people in the industry. I am in the industry as I told Ben, if there is something I should do, add to my signature etc, please let me know but I am NOT selling anything. If you need to email me for any reason it's john@le-pre.co.uk
Hope we can continue.

Would you believe I don't have access to that?

Teapot, you do not have permission to access this page. This could be due to one of several reasons:

1. Your user account may not have sufficient privileges to access this page. Are you trying to edit someone else's post, access administrative features or some other privileged system?
2. If you are trying to post, the administrator may have disabled your account, or it may be awaiting activation.

Whoa! I don't get that! And I cannot change it.

Forum Rules (Acceptable Use Policy)

PoolForum AUP
updated May 2012

Participation in the PoolForum is subject to certain conditions.

Violating any of these conditions will result in your membership being terminated, without refund if you've subscribed. Please understand that I -- and I alone -- am the final arbiter of whether you did, or did not violate the terms. Let me warn in advance that individuals in the pool industry have typically found it very difficult to abide by these terms. (See below for further notes for pool industry members.)

That said, here are the conditions:

Don't sell or promote stuff!
This is the #1 reason people get banned, and it's the reason people in the trade can't abide the rules. Sell stuff -- and that includes statements like "my product is best" -- WILL get you banned instantly. Promote stuff -- "I think my new super duper Whiz-a-rink sanitizer is what everyone ought to use" -- and you may get a warning, or you may get banned. Spammers, hackers, promoters . . . get banned with NO refunds, if they've subscribed!
.
Be polite, kind, and respectful.
Personal attacks and ad hominem arguments will get you a warning . . . once! Cussing, obscenity (remember I judge), lying, and the like will get you banned instantly. Use language acceptable to your 2nd grade teacher, your Sunday School teacher or your old maid aunt! Even though I'm from the south, 'red-neck' vocabulary is not allowed here, and will get you banned.
.
Be nice to newbies.
Remember that everyone was once a newbie -- always be polite and kind when newbies ask the kind of stupid question you once asked, too. Even when it's necessary to tell them to stop being so nervous, and posting new questions every hour, and to just go and do what they've been told . . . DO IT NICELY!
.
If you're in the biz, say so!
If you are in the pool industry -- as an employee, owner, partner, representative, contractor, manager, consultant, engineer, etc -- say so clearly. We'll move your membership into the special pool section, and let you start there. If you do not disclose your pool industry role, you'll almost certainly end up banned sooner, rather than later.
.
Post questions, don't PM them!
Private messages should be for *personal* communications, like 'how's your sick cat doing?', not for pool questions that should be posted on the forum. Also, please keep in mind that PM's are not utterly private: I have the database passwords, and see all PM's when doing certain types of maintenance. Don't use PM's for things that need to be totally private.
.
Don't tell me you are not a spammer!
because it's useless to do so. Everybody says that, including the spammers! In fact, the spammers go to great lengths to try to prove to me that they are not spammers . . . so I will let them in far enough to allow them to blitz the forum with spam.

So unless you know me personally, your statements that you are not a spammer don't tell me anything. The one thing you *can* do, to prove you're not a spammer is to NOT be anonymous or bogus. Anonymous registrations are very unprivileged; the only thing worse is registrations that contain bogus info.
.

These conditions help preserve the value of the Poolforum for everyone. Please support them.

Thanks,

Yep I remember a couple of paragraphs when I was emailed by Ben, especially "don't sell or promote stuff" I thought I was already in the special pool section as Ben or a Mod had to approve my first posts. If you need/want me to add something to make it clear to my signature etc please say so or can you carry that out? Just trying to be straight.

Your pool looks good Richard but there is extra electricity being used for the booster pump for the pressure side cleaner, I just use a Pool Blaster max now days although I can of course use the old vacuum head and hose should anything happen but it hasn't and less work is required now to look after the pool.

Richard uses ThePoolCleaner (I do too) which does not require a booster.

Just like Mark's study on turnover it appears we need a lot less turnover than previously thought. If I had less trees I would almost certainly reduce the run time but as I said you can only skim the surface if the equipment is running.

It was actually Ben who found the study.

Apologies Mark & Richard I thought that was a Polaris, That model of cleaner hasn't made to the UK or Europe as far as I know. How do you rate it?

Ben, Legend!

I switched to 4-wheel pressure The Pool Cleaner when I switched to a Pentair Intelliflo VF pump. Prior to that I had a single-speed pump and a separate booster pump for a Letro Legend pool cleaner. I'm very happy with The Pool Cleaner, but I have a cover on the pool most of the time so don't get a lot of debris. I clean out the cleaner bag no more than once a week and can usually go longer between emptying the bag. When the cleaner is on, it's at 15 GPM, 2180 RPM, 540 Watts for 2 hours each night (I have a Jandy valve that switches the main pump to a dedicated line for the cleaner). I don't need to run it that often, but I never know which day is going to get the debris and my wife swims nearly every day and doesn't want debris in the pool. When the solar is on at 48 GPM that's 1500 Watts and when it is off at 26 GPM it's 300 Watts.
