Pipes will not burst, if u got the right person to do your plumbing work, there is no way pipes will burst. For landed properties with 4-5 bathrooms the best pump to get is Grundfos CH2-50PC.

Landed property will definitely have weak water pressure as the water flow down from the tank which is 1-2 story above your bathrooms, the gravity pressure is weak. Condo on the other hand have strong pressure bcoz the water tank is like 5-10 floors above your unit, so the gravity pressure is strong and you will have strong will have strong water pressure

Modern negative ionizers work by using a method called ‘corona discharge', which is actually modeled on the way lightning occurs. A tiny current of electrons flow down a needle to its point. The nearer the electrons come to the needlepoint, the closer they are forced together.

Since electrons naturally repel each other, when they reached the very tip of the needle they are forced off into the nearest air molecule and become a negative ion. Negative ions repel each other as well, so as more and more are produced they are emitted further and further out into the room they are in. The more powerful the ionizer, the more beneficial ions they can produce and the larger their range.

On take off, the vane is closed pinching the exhaust flow down to the smaller end of the turbine housing scroll before it can impact the turbine wheel with more force at lower engine rpm's. Using the vane lets us use a larger turbine housing than a conventional turbo would need to get low end performance and then open up the vane to get better top end performance with the bigger turbine housing.
