Facts from wikipedia
Home remedy drain cleaners include boiling water poured into drain openings to clear soap and hair clogs; or, baking soda (sodium bicarbonate) poured into a drain, followed by vinegar.7
Advantages of home remedy drain cleaners include ready availability and environmental safety, though they are limited in effectiveness compared to other drain cleaners.
Safety considerations for home remedy drain cleaners include the requirement to handle ingredients (for example, boiling water) with the appropriate care.
Chemical drain cleaner
Chemical drain cleaners can be in solid or liquid form that are readily available through hardware stores, though some (primarily acidic ones) are intended for use by licensed plumbers.1
Alkaline drain openers
Bottles of alkaline drain cleaners containing sodium hydroxide can dissolve greases and hair.
Alkaline drain openers primarily contain sodium hydroxide and some may contain potassium hydroxide. They may appear in liquid or solid form.
Liquid formulations of corrosive alkaline drain cleaners can contain sodium hypochlorite (bleach) and lye (sodium hydroxide or potassium hydroxide) in concentrations up to 50 percent. Other corrosive mixtures come as two-part cleaners that are mixed as they are poured in the drain opening. Inside the drain the two solutions react to release a gas, and surfactants trap the gas as dense foam. The intent of this foaming action is to coat the inside of the drain pipe to dislodge more of the substances that form the clog.
Solid formulations of corrosive alkaline drain cleaners in the form of sodium hydroxide or potassium hydroxide granules can provide more concentrated effective ingredients. Some patented, solid-formula cleaners add aluminum turnings that react with the solid hydroxide in water to heat the caustic mixture to a boil.
Alkaline drain openers can dissolve hair (containing proteins) and fats inside pipes via alkaline hydrolysis of amide and ester respectively:
RCONH2(amide or proteins)+ OH? ? NH3 + RCOO?
RCO2R?(ester or fats)+ OH? ? R'OH + RCOO?
Accident prevention hydraulics
Everyone knows perfectly well that it is much better to prevent failures hydraulics rather than repair them. To that just might be, it is the right approach to these issues and the efficient use of hydraulic installations, so you should find out what it is. First of all, at the beginning we should take care to choose a good system, a proven company and its installation to hire professionals. Later you need to be more regular periodic reviews and monitor the status of pipes and other parts of the system, and if you get even a small problem, it is always worth call a specialist, who immediately take care of him. Thus we avoid serious accidents which repair is often very expensive.
