    Evaporation or leak

    Ah thanks Marty, yes the pool temp is largely the same but the ambient temp has dropped from 75 or so to 50 or so. as you say the cover will reduce it so maybe that’s not the whole reason. It’s not masses and masses being lost but enough to make me wonder if there is a leak.

    Evaporation or leak

    Given COVID am running the pool later and maybe over winter. Bit worried my pool has developed a leak. I now seem to need to top it up more frequently than I did in the summer. If ambient air temperature is lower should I be getting less evaporation not more or is it the other way around?! I...

    Weird surge from a return?

    Could it just be the way the water turbulence is changing over time? I don’t get what you have but I do get little whirlpools appearing and then disappearing. Have you put your hand in front of the jet and noticed a change?

    Master temp 125

    Yes it seems to work without errors when I first set it. good shout for the pump. I did make that mistake once before Leaving the timer set and boiled the water in the heater when the pump stopped, so now I put the pump on manual when I’m running the heater. So if the pool is 77 say, I set...

    Master temp 125

    Thanks - I’ve only got a heater unit. I haven’t got a remote so the only controls I have access to are the little panel on the heater itself.

    Master temp 125

    My heater a master temp bc 125 seems to switch off before reaching temperature. So if I set it to 84 say it tends to switch off at 82. It doesn’t always do it, sometimes it will heat to temp set. Pump timer Is off so not being caused by pump switching off. Any suggestions?

    Skimmer

    I take the basket out and put the hose into the open skimmer port to vacuum. How do you calibrate the skim/sump mix? I have just one return which is at the same end as the skimmer. I don’t really get a problem with stuff in the pool surface, I get a few bugs that end on the bottom(but I...

    Skimmer

    I do have a vacuum port that is shut off (as I understood it leaked) do skimmers get connected to these? do I need to worry about balancing via the shut off valves in some way?

    Skimmer

    Thanks TS. Im fairly sure the main drain does work as I have a separate suction line with shut off valve to the pump ( and If I shut the skimmer off the water still circulates). I have a floating basket within the basket but sounds like I need to get a weir door too, problem is I’ve no idea on...

    Help with pool configuration - skimmer& drain

    What are the chances. I have exactly the same question as I have a similar plug. Watching with interest :) I do have separate lines and shut of control for sump and skimmer.

    Skimmer

    I’m wondering if my skimmer is set up right. It looks like this It looks as if the sump balance is blocked off. What are the implications of this? I don’t have a weir door should I? I also don’t seem to have a balance device to sit on top, albeit this wouldn’t work given the balance is blocked.

    Lacron sand filter

    So changed the gauge today. No water leakage, just air got in. Even though I set the multi port to closed and Other valves to closed I think it was draining to waste. a couple of minute job and so far all seems good. I can now see a pressure (around 16psi/1.1bar so will see how that changes...

    Pump timer and heater

    Ajw- sorry yes Celsius is how it’s set and what we tend to use in the UK. I forgot to convert. I have the pump on a plug in timer so sounds like I could put the heater on a timer that finishes 5/10 mins before the heater. The heater does seem to still ‘run’ for a bit after shutting the gas down...

    Pump timer and heater

    The other day I noticed my pentair master temp was showing 45 on the display. I thought help that must be an error code so I fired up the pump to see if the heater would come on. When I did the number fell. So I think what must have happened was the heater was on and then the pump timer turned...

    Lacron sand filter

    Ah yes good point! I do, I think. Each of the skimmer and sump have separate isolation. There’s also another in one of the flow pipes either to or from the filter.

    Lacron sand filter

    Could I set the multi port to closed or do I need to do some draining down? or perhaps both?. My pump/filter is in a shed so can’t just let the water pour out.

    Lacron sand filter

    I have a lacron sand filter many years under its belt. Only been in my ownership for 6 months when I moved house though so don’t know its history. Id say the filter is 30 years old. No idea if the sand has ever been changed. It seems to ‘work’ but the pressure gauge is 30psi, pump on or off...
