I believe that they need to be at least below the bottom of the skimmer so that, if the waterline were to drop below the bottom of the skimmer, the returns would not run dry. In my pool they are about 15-18" below the usual water level.
Waterline corrosion: when water is stored in a metallic tank, it is observed that the metal below the waterline gets corroded. It is because the water below the waterline is poorly oxygenated and acts as an anode. The metal above the waterline is highly oxygenated and acts as a cathode. Hence corrosion of metal below the waterline takes place.Any other questions skype mechristianschulte6474or email me at schultechrstn@aol.com
Height from the waterline to the deck is "freeboard." Above the deck is superstructure, and below the waterline is draft.
It is the depth of the hull below the waterline.

Draught or Draft
You should denude flower stems below the waterline.
France, there are actually Alps there! Holland is pretty much below the waterline.
Absolutely; it makes no difference whether or not a boat is submerged or not, as the torpedoes are water-impulse ejected out of the torpedo tube before engine start, and the tubes are literally about 20' below the waterline of a boat you see surfaced. Fully 3'4 of any surfaced boat is below the waterline that you don't see.
All platypuses dig their burrows above the waterline of creeks and rivers. The entrance is not below the waterline. During flooding, water does get into the burrow and the chamber, and baby platypuses that are still dependent on their mothers can be drowned in these instances.
TDBFP return drain is going to condenser hense TDBFP position should be above condenser elevation. If it's below turbone then return drain flow may be restricted. Sachin
On average, about one-third of a cruise ship's total height is below the waterline. This submerged portion includes the ship's hull, which is designed to provide stability and buoyancy. The exact percentage can vary depending on the ship's design and purpose, but generally, the underwater section is crucial for the ship's overall balance and structural integrity.
For tiles that are installed below the waterline in pools, a thin-set mortar specifically designed for wet environments, such as polymer-modified thin-set mortar, should be used. This type of mortar is formulated to withstand moisture and provide strong adhesion in submerged conditions. Additionally, it is essential to ensure that the mortar is compatible with the specific type of tile being used, whether ceramic, porcelain, or glass. Always consult manufacturer guidelines for best results.
