- Q: Hi guys, Thanks for your advice. RandyK is right, my dad's GP told me that if we don't get the valve operation, his heart will swell in years time and might cause more complicated illness. Just let you know my dad had seen his cardiologists recently and had some scan or tests done. The results will be discuss in next appointment, they suggested that mechanical valve would be used if the operation go ahead. At the mean time I just hope and pray his condition will under control by medication. Wendy, may I ask you how old are you when you had your valve operation? I am too scare to suggest or encourage my dad to do the operation. Because if there is any difficulties or worse ...during operation, I will be the one send him away......If anyone have a relative like my dad's case,(76 years old had valve operation) please give me some advice.. Many thanks
- Hi David, just saw your post. I was young when I had my valve replaced. I was 37, now am 42. My mother had her valve replaced at the age of 54. Honestly, that is the oldest person I know of that has had valve replacement. As with any surgery, there are alot of risks young or old. The older a person is though it may be tougher especially if he has a lot of other health problems. Just take all of this into consideration when you and your father are discussing all the details, etc. and find out any and all options that he has before proceeding with surgery. Best wishes to you both.
- Q: So i finaly got my check valve and my airstone. The airstone is actually a flat round airstone and is 5 inches in diameter to be in my 10gallon. Is it to big? though i have a tetra whisper air pump for 10-30g.And how do i place the check valve? Do i put it closer to the tank or closer to the pump? (just to make sure since i heard so many different ways people put it). Or does it even matter?And lastly, do i put the OUT side of the check valve facing towards the tank or the pump?Thanks! after this im ready to install it!
- Adequate the purpose you let a tank cycle in the first place is due to the fact of Bactria needs to grow that will maintain your water clear. As for overstocked. I consider your proper on the threshold of being over stocked. Just preserve the tank walking a lil longer and spot if it clears up. But when your 15 gallon tank has the filter from the ten gallon tank that could be why to you dont have sufficient water moving around to scrub it

- Doleful is an adjective which means that it describes a noun. Similar words include: dreary, forlorn gloomy, grieving, lamentable, melancholy, mournful, pitiful, plaintive, sad, sorrowful. It was a very doleful day for Mary when she had to leave her friend behind. Lament is a verb. It means to grieve or to bemoan the loss of something. Frank lamented the death of his beloved cat. Woe is a noun. Other words meaning the same thing are misfortune, sorrow, suffering, grief. misery. Woe to the person who breaks his promise to me. Their woes became unbearable to handle.
- Q: I know i have to buy a recirculating valve but should i drop 250 on the perrin or will any brand do? how important is a high quality BOV?
- Go with the APS blow off valve. As for the idiot who said name doesn't matter, let him go buy a $20 BOV and have i the diaphragm start leaking at idle and cause tons of driving issues.
- Q: behind the valve cover of the #1 and #2 cylinder there are 2 intake and 2 exhaust valves I need know (cylinder #1) which is the intake and which is the exhaust. thank you in advance.
- 1. Intake valves are usually larger than exhaust valves 2. Exhaust valves are on the same side as the exhaust manifold
- Q: Hi, I'd like to control a three way solenoid valve like this one:understanding is that an electric current through the solenoid will cause the valve to let air one way while no electric current will have the air flow the other. Is there a piece of equipment like a control box (that can communicate w/ a computer) that would allow me to control the solenoid valve like this? and if so, where would i be able to find something like this....i've googled but no success. I eventually want to control the valve from a computer. Thanks

- Q: In one of the two bathrooms - that we rarely used - I recently found that shower has now only hot water running. The valve is Moen brand with a single knob. On turning this, I get no cold water, but just hot water. I removed the knob, and decided to maybe replace the cartidge, but could not make any headway, after removing the acrylic knob. First, do I need to remove the cartridge?If yes, how? Is it possible to remove it without removing the back-plate glued to the Tile walls? Will appreciate detailed instructions to remove or fix the valve?thanks

- Q: Can anyone tell me what to do if i know that I have the type of valve stem that was recalled TR413chrome?? Will they replace them for free since they are a recall or do I have to dish out some more $$ to fix the problem??? The company that sold them to me is in Florida (Wheelmax) and I am in Mass. Not sure what to do to avoid having to pay out more $$ to have them replaced...any help is greatly appreciated
- The recalled valve stems were sold under the Dill brand name - it should say Dill on the package if you have extras. If you go to the link provided above they will have additional information. This is a VOLUNTARY recall being performed by Dill, the American distributor for this particular line of Chinese made valve stems. All roads for the recall therefore lead to Dill.
- Q: My car (RWD) has vacuum leak and has the code PO171/PO174. I find some engine oil at the bolt well of the valve cover on the bank 2 side. Can the vacuum leak come from the valve cover? What is the main function of the valve cover? Thanks.
- Valves and the cam or rocker arm assemblies on top of the cylinder heads are lubricated by engine oil that is pumped or splashes up from the crankcase. Valve covers just contain the oil and keep dirt out of the engine. Vacuum comes from the intake manifold, and is routed to various locations through small flexible rubber hoses. A vacuum leak is probably from one of those small rubber hoses that has cracked or come loose.
