thanks for your comments, yep suck from main bottom drain (dedicated line) would make sense

hello, putting together a new pool build and pump house and want to plumb in an emergency fire fighting outlet using pool pumps and water from pool. Have two pumps, main 1.5 hp pool pump and booster pump for polaris. Pool pump has volume, while booster gives greater pressure on lower volume. Any...

thx poolman, will struggle to get check valve in before pump (space), so will probably put it between pump and filter. Also was worried about leaves etc clogging it, so water should be free of debris after pump strainer. Once system is primed and full, am I right in thinking (if leak free as in...

good morning, new pool build happening (in ground concrete) and pump house is about 25m/80ft from pool (yep best solution) with pump about 1m/3ft above water level. Pump is a Poolex Variline VS 1.5HP, which is self priming, manual states do not exceed max 3m/10ft lift (pump above water level)...

@Bill1974 that's an approach i get, building something to do the job properly. That (stainless fitting) should last a while. I might end up with those floating lights....:)

Like the blue, looks great, but still has electricity in water bit....

have had a few pools over the years and have never had TF lights, fix 'em and they work for a bit. So I'm a bit anti lights (from trouble pov), but like the night time scene when working. Presently on a new build (inground concrete)and one side of the pool is above ground (land is terrassed), ie...

thanks all for your input

well that's what i'm trying to establish (rogue currents). SWG maybe, salt water, dissimilar metals - if not in the pool my house has aluminium and copper and steel and all sorts in the water system. I'm a boat man and I know salt water and different metals causes problems, and i'm trying to...

Reading around I found some threads on galvanic action, and my reading of this (for pools anyway) was for peace of mind install some zinc anodes, but generally galvanic action in pools was pretty insignificant. With a water link to a house with more metal (taps and fittings and washing machines...

Thanks for replies, yep backflows and avoiding possible water contaminations will be taken care of, but my 'worry' is about rogue electrical currents and metal fatigue via galvanic action. Is that an issue in pools/connected houses via a water link. Perhaps a pvc pipe and pvc backflow valve will...

Hello, at the design stage for a newbuild inground concrete pool about 50,000litres, with SWG. Previous pool had an auto fill system which used a redundant sprinkler zone feed, rerouted to squirt water into the pool from pool house roof. Air delivery. A few minutes a day was usually sufficient...

Poolgate, I can't see much wrong with your suggestion. Will definitely check with local authorities because they will help......:)

FYI pressures up to max 6 bar unregulated, regulated to feed house on 3 bar (43psi)

Hi and thanks for replies. I am in rural France and do not know the reason for the two separate (metered and valved) lines. (Used to be two rates too here for domestic and irrigation; but no longer.) Through this first winter in the house water supply on one single supply is good. But as I want...

my house has two independant metered water supplies in 1/2 in steel pipe coming onto the property. Not going to alter that (1/2" bit) because just too big a job. All is fine except previous owner said water flow/pressure drops off in the summer. As I'm into getting things put right I am thinking...

thanks all for your input. The house is old but the plumbing right through to and including tank, all new, Drain field existing and working. All pipe falls, bathroom connections good, tank install as per local code, except secondary air venting in the hedge - it should go back to roof level...

System all good and clear - brand spanker, installation on code except for vent in the hedge Have popped an aerator/air valve on the roof exit vent....let's see what happens

Was recently in a rental house with pool with SWG. I've had a few pools with SWG and one of the issues is jiggling pump run times to keep up with required cl production. This rental house had a SWG with variable chlorine production, so pump time could stay fixed and cl production could be...

Chris - many thanks for your comments. I think our systems are in fact quite similar, my single tank (some kind of plastic) does have two chambers for liquids/solids :oops: but air can circulate above the water line. When tank is more than 10m from the dwelling we need to put in a grease trap...

Hi and thx all - read the other thread and my queries are more venting/chemical :) New septic tank (single unit 1000 galls taking all household waste) and has been running from new for a family of 3 for about 6 weeks, and all seems pretty good - waste in, 'water' out soak away etc. etc. No...

this site was great helping me sort out pool related issues, and I was wondering if any of the expertise available covers another kind of pool - my septic tank :oops: If anyone can help would be happy to post the details

thanks for all your comments. To Pool-Medic.....not sure I understood the conclusion of your experience, better with or without CYA. It seems from the comments the SWG will work without CYA, but has to work more to cope with high loss of FC to UV burn off. Onto water conform, mknauss I think...

good morning have just refilled the pool as CYA was over OTT. Went to purchase salt (ok) and CYA - not so easy. Both suppliers don't sell it. Explanation SWG pools don't need it. The specialist in the pool shop said he'd been running swg pools for years without CYA. Why did I want it? With...

Thanks TS for your comments. Looking at your Cl/CYA charts i think i've been running too low a FC level. Pushing it up as we speak and pool looking better. On the disolved marble, just wondering if the milkiness (which seems now to be less visible) could be some kind of marble residue in...

Hi all, year three with my inground pool...its getting easier but I'm not quite there yet. Here are my readings pH 7.12 FC 1.23 TC 1.58 TA high (off scale) CYA 70...

Is this a pool fundamantal? Once algae is visible you have no choice but to SLAM? Once slammed successfully what is a primary pool condition for new algae appearance? Low CC?

Thanks ping for answereing my queries. MD

Mmmmmmm.......just checked and found no difference between the readings on my Aquachek color dippers!!!! (SWG was producing, not on rest cycle).
