they can run in parallel? that is a great news because i left exactly half of roof space open. i feel like a genius now.

I seen you can buy Deye inverter on lazada and its advertised as PEA approved. Has zero export feature. My question is a feature or is it forced by PEA so you cannot export? I wanna be able to export to keep my bill close to zero. i almost decided to go ahead with solar system got nice quote from Facebook group seller. 12 x 450w n type panels of my choice with deye inverter installed on my high roof for 113 000B . i think it sounds great. I think i will skip battery for now. i might do DiY battery for half the of price later

good read how its done in Chang mai https://lenhend.com/building-in-thailand/septic-tanks/ i found this picture in it along with explanation. still don't know point of that P trap under ground because already got one under the sink. that curved connection between 2 wells i wonder if its optional and should be used in my case

Ok guys thanks for advice it seems clear to me that i have to: -Add another gray water concrete well -get rid of T connections -get grease trap for kitchen sink i guess if i have a clear plan ( and parts) i should find somebody to just follow the instructions and help with labor.

i like the idea of French drain around the house to get rid off excess roof water that might help with my problem but i still feel that this septic system should work better and is messed up

there is a vent pipe installed on black plastic tank that is all. toilet 2 is not connected to smaller pipe next to it. Just appear so in this picture. angles of slope are small I do not like that.... i agree that T connect is bad it should be Y connected to toilet 1 and 2 I saw some people have 2 concrete wells separate for overflow septic and separate for gray water.... i don't know if that would my fix problem but seems it would give more area for water do dissipate into ground . and at least that would give me opportunity to fix connection to septic tank.

we are already on high ground see neighbor below in the background. i think we really should have 2 of those concrete wells but builder skipped this step

So house has 2 bathrooms , kitchen, bar sink and laundry. I took this picture when it was built. I thought people that "did that" know what they were doing. So fast forward 2 years later during rainy season showers and toilets drain slow but still works. But this year kitchen sink water comes up and drains super slow... sometimes clogs and stays there for hours. . Mind you only 2 people live in this house. Here is what I think : I need another concrete well , everything reconnected the way it make sense and maybe grease trap for kitchen sink. I don't really know who to ask and hire but this time i really have to know that its "done right" So dear members of community please advice
