Ok, so the one not pulling obviously goes to the main drain, if it goes anywhere.chiefwej said:One pipe comes from the main drain and the other goes to the pump. There should be a diverter plate in the bottom of the skimmer under the basket.
Bama Rambler said:Those let you adjust the amount of water coming from the MD. But first you need to make sure the main drain is connected to the bottom of the skimmer. Do you have separate pipes for the skimmer and main drains at the equip pad?
brainchasm said:Yeah, I saw those, but they look to be 15% or less. Trying to work smarter, not harder.
brainchasm said:So, with only the one pipe, the main drain HAS to be routed through the skimmer (#2 hole), and I just need a spaceship or a twinkie. Recommendations on either, and their proper names so I can do some shopping? I'm really betting the twinkie is going to be the way to go...
I appreciate your concern. I've worked with and handled scary chemicals a fair bit, usually in a cleanroom/lab situation. I'm ok with normal-scary stuff (but not crazy-scary stuff, like http://pipeline.corante.com/archives/things_i_wont_work_with/.ike0069 said:brainchasm said:Yeah, I saw those, but they look to be 15% or less.

Forgive me for butting in on your thread, but I wanted to comment on your above statement.
First, I purchased a 2-pack from Lowes last spring and it is 31.5% HCL. This is VERY stong acid and a weaker solution would be preferred, especialy for a smaller pool as yours. I have a 6000 gal salt water pool that steadily increases in pH. My pool was open for ~ 5 months last season and I used about 20% of the bottle, so one bottle will last ~ 5 years.
FYI: I sell industrial water treatment chemicals as a profession and Muratic acid can be scary if not handled properly. Muratic acid is hydrochloric acid and gasses off (chlorine gas) at ambient temperatures. The strongest available industrial strength is 38% and requires a fullface respirator to use as it fumes so badly, and the 31.5% I have definitely fumes. A 15% solution would be much safer, and while you would use twice as much, the safety factor should be heavily considered IMO.
