there are no one way or check valves on this model . i have watched it shut off at various times and its does not seem to be a flow issue as its flowing well at the time of the shut down . it shuts off on low speed as well as shuts off during high speed as well and there's for sure no flow problem then on high speed .

there is no one way or check valves in this model

has any of you ever seen the top side control cause an issue like this ?

alps spa everest , 2018 year model

with the 2 filters removed . good suction . i don't think this tub has any check valves

Didn't change the topsides . but have checked the ground and incoming power.

right at 5 year old Alps spa .led lighting package 2 - two speed pumps with all balboa controls and spa pack . things i have tried : new spa pack * complete pack* (two times) new primary pump 2 speed pump *low speed is circulation* ( two times) running without filters installed ( no change) disconnected ozone generator disconnected secondary control panel second 2 speed pump is original found the earth ground 9bare copper) a little weak ,installed 2 new ground rods, but that has also been repaired with no change . OHH keeps coming back , sometimes several times a day and sometimes just once a day . this happens at any set temp , it will do it when set at 96 degrees just like it will at 104 degrees. filter cycle is set for 4hrs 2x a day , has 2 cartridge filters

Having a pool for 12 years and hottub for about a year. i have found my grand daughter is sensitive to Borax , makes her break out and itch

I have a two week old hot tub , Acrylic 425 gallons . Its been having severe PH bounce , i keep it on7.4- 7.5 and after a soak it jumps up to 8.1 and sometimes over night it jumps up , I have used an entire bottle of ph down in the last 10 days , at fill i added a bottle of ph buffer , where i was keeping it . Ph (bounced) TA 120 CH 150 Br 4.0 temp 100 degrees was using bromine with Di chlor , metal out once a week , enzyme once a week , , and after not using the tub for 3 days , the inside is suddenly really rough , esp in the corners and around the jets. What i have done so far. lowered PH to 6.8 Ta 80 CH 150 Br 4.0 temp to 85 degrees , and added a triple dose of metal out Ace brand Is there a product i can add ? I'm very concerned about the build up in the plumbing and heater unit . HELP please
