A. First, unscrew the aerator from the end of the spout. Be sure to hold the screens in and flip it over and backflush it. While it is removed, see if the sound is still there. If so, there is probably a bad "O" ring in the cartridge. You can replace the whole cartridge cheaply. Just remember the position it was installed in when replacing. You can mark it with a felt tip marker for reference.

A. Can be opened or closed remotely without complex 3 to 15 pound instrument air control plumbing from the control device, all through the plant, and hoping there are no air leaks in the flimsy copper tubing. Rate and amount of opening/closing can be controlled accurately.

A.

The night before the operation is scheduled you will get a visit from a number of professionals including-- Surgeon Anaesthetist Pharmacist Physiotherapist Lab Tech --to take a blood sample to cross match 4 units of blood !!

Q. what is the operation of the cabin pressure outflow valve and cabin pressure safety valve.?
Asked by Mayowa S - Sun May 25 02:51:08 2008 - - 1 Answers - 0 Comments
A. You need to be more specific in asking the question, however; Outflow Valve is a valve that regulates the amount of air needed to be released (or on the other hand, to be kept inside) from the cabin in order to keep the cabin in a required amount of pressurization. A safeguard to protect the aircraft from being over-pressurized or under-pressurized is by employing safety valves. When the differential pressure is too high and the outflow valve fails to rectify the situation, the safety valve opens, reducing the cabin pressure. Likewise, when on the ground, and the cabin pressure is lower then outside air pressure, the negative pressure valve will equalize the situation.

Valve-replacement operation? (Open heart surgery)?
Q. Someone I am very close to will be having this operation, and I'm very scared about risks. When my grandad had this operation it was a big shock for the whole family because he had to have it the day after he got told he needed it, and there was a 30% chance he wouldn't make it. His risk was high because he was diabetic, a smoker and 80 years old. The patient is 50 years old, is asthmatic but otherwise has average health and does a little bit of exercise each week - 20 min runs about twice a week. Can anyone tell me whether the risk will be big this time? Are these operations really that safe? Is it possible the body will reject the new valve therefore the operation will fail? Thanks for any information.

A. As with any surgery, age and overall health plays a large part. The fact the patient is active and is in otherwise good health is always a plus factor. Asthma is rarely a problem. Valve replacements are not considered major surgery anymore, they are very common and have high success rates. With regards to your Granddad, you need to take into account his age, the fact he is diabetic and a smoker, all these factors have a negative impact on any kind of surgery and recovery. Valve replacements are usually done via keyhole sugery. Which type of valve is he having? The operation takes about 2-3 hours and afterwards he will be taken to ICU before being taken back to the ward. Some valves do need replacing, the older artificial heart valves… [cont.]

How does a solenoid valve work?
Q. Hi everybody, I need some information about the operation of a double solenoid valve and how to control it using a PLC
Asked by Sharaf - Sat Oct 4 03:29:57 2008 - - 1 Answers - 1 Comments
A. A double solenoid has two solenoids, and when voltage is supplied to one (and not the other) the valve shifts. Note that if voltage is supplied to both solenoids at the same time, the valve will stay in the position is was in (i.e. it won't shift since the solenoids will be working against each other). This is typically not desired, so make sure you remove voltage from one side when supplying it to the other. If no voltage is supplied to either solenoid, the result will be the same as if voltage is supplied to both, in that the valve will stay in the position is was in. What this means is that the cylinder has no home position, so when power is cut, the valve will stay where it was at that time, and the cylinder will continue to do work… [cont.]

A. Could you re-edit with which valve has been replaced, the age of your mother and any other relevant medical history including general health. Basically, heart valve repairs and replacements are pretty safe nowadays, however the operative risk does depend on other factors too. Is your mother having open chest surgery or keyhole surgery? The latter has a quicker recovery time. With keyhole surgery, rather than making a cut down the sternum, incisions are made without opening the ribcage.

Asked by Chaun - Tue Aug 29 09:27:23 2006 - - 5 Answers - 0 Comments
A. Valve cover gaskets fit between the valve cover (on top of the engine) and the cylinder head (middle of the engine). It's purpose is to keep a tight seal between the two and prevent oil from seeping out. A failed gasket will at least let some oil out creating a smokey smelly mess. If it lets enough oil out, you may run the risk of spilt oil catching fire. Using your car with too little oil and / or inadequate oil pressure can cause major engine damage. Replacing this gasket on most cars is quite easy and inexpensive. Its not a very serious problem as long as it gets taken care of soon.

Still one thing you could try before calling an engineer is as follows. Turn off the water supply to the dishwasher and remove the hose, turn on the machine for a couple of minutes in a fill position then turn off the machine, reconnect the hose, turn the water back on then turn the machine back on. If this doesn't solve the problem, then you will need to call an engineer. Good luck.

should she proceed with the operation or postpone it?
Q. my aunt is scheduled for a keloid operation on august 11.. they will be doing skin grafting. she had a heart valve operation 12 years ago so there's a big scar on her chest. the doctors told her that the valve will be changed after 15 years. she's worried that a keloid will form from the skin graft site and she's also having second thoughts because if they'll fix the keloid and then she'll have the heart valve operation again in just 3 years from now.. is it worth it? we just want to know your thoughts on this :) thanks!
