    How to check a leak in the air bubble line?

    100% short cycle vs 50% long cycle

    Hi all, I am new to SWG. I will install a timer just for the SWG. Just wonder if I should run the SWG at 100% in a short cycle or at 50% in a long cycle. These are my considerations: 1. pool chlorine fluctuation. short cycle = higher fluctuation. Is it harder too keep the pool clean? 2...

    Ok to leave the system in AUTO when there is no flow?

    Hi all, I have a Hayward salt water chlorine system. My pump has an internal timer, so it does not use the external timer and it is always on. The salt system connects to the same load, so it is also always on. My pump does not run at night. Is it a problem for the salt system to stay in...

    What is the max water level relative to skimmers?

    We had a few heavy rain storms recently. The water level is higher than the top of the skimmer opening in the pool. As a result, water is not being skimmed. I assume we want to keep the water below the top end of that opening, right? Sent from my Nexus 5 using Tapatalk

    Cracked grout leads to small leak

    I have some small hairline cracks in the tile grout lines which lead to dampen the coping stones. Some people recommended eproxy grout but it is not really recommended by the manufacturer (mapei). I put some clear silicone caulk at the corners and it seems to help some. Just wonder what you...

    suck wate from both SPA and pool at the same time?

    Hi all, I think this question has probably been asked before but I can't find the answer in search. Anyway, can you draw water from both SPA drain and main pool at the same time? My SPA has a spillover. I am thinking it may improve the circulation in the SPA... On a different note, to...

    Questions about balancing pool return flow and minor leak at tile grout

    Hi all, My pool has 5 returns tied to a loop. The 2 returns closest to the pump have much stronger flow, as expected. In order to balance all 5 returns with similar flow, do I need to decrease the eye ball size of those 2 fittings from 1" to 3/4"? I notice there is a vertical crack line in...

    My PB just installed the blue granite pebble sheen on Tuesday and acid washed on Wednesday. After the SPA is filled up, I noticed a big round mark in one of the drains. It looks like the pebbles are more exposed in the dark area while the rest is not as exposed in the light area. Did my PB...

    ball valve between pool pump and filter in a flooded system?

    Hi all, I bought a house with a pool and we are getting ready to fill it up. The equipment pad is located 10 feet below the pool water level. I think people call it a flooded system. If I need to clean the leaf basket in the pump, does water flow back from the filter to the pump? If so...

    Re-tie the rebars after they are cut to clear way for repair?

    Hi all, I am resurfacing my pool and SPA. My PB accidently broke one PVC pipe in the SPA floor. To make room for repair, he cut 3 or 4 adjacent rebars in the concrete. Does he need to re-tie those rebars so that water does not crack (force outward) the SPA structure once it is filled with...
