Q:Why can't sprinkler system and hydrant system share water pump in fire fighting system?
The design code of sprinkler system GB 50084 - 2001 (2005 Edition) stipulates that the sprinkler system shall be provided with an independent water supply pump, that is, the water pump shall not be shared with the hydrant system. The aim is to ensure the reliability of the water supply and prevent interference.See the code for design of automatic sprinkler system, GB 50084 - 2001 (2005 Edition), 10.2.1 and the corresponding provisions of the following interpretation.
Q:Cost of water pump replacement in 2001 PT Cruiser?
They vary in price but at the right auto parts counter you might find a brand new or rebuilt water pump for about 75 bucks or so but no more then about 160 bucks.The labour on those takes a few hrs anywhere from 4 to 6 hrs or less all depends on the tools and the mechanic. Check around for the part and the labour costs and sometimes it's better when it's a job like this that will cost at least a good 275-400 in labour costs plus taxes to have the shop supply or sell you the part bec then the shop truly should warranty the part via their part supplier and warranty their own labour work too.Also some shops here in Canada charge from 69 to 89 an hr or higher but there are also some shops that will offer a flat rate for work done by them too.So if you have a shop wanting 80 an hr and to charge for 6 hrs or more they could end up charging you well over 600 bucks just for the labour alone. Hope that helps and best of luck.By the way if you do end up deciding to fix that vehicle there could be some shops in the local smaller towns that might offer you the lower rates due to them being family operated or owned etc and I'd try to find a shop that has done lots of that same vehicle make work.
Q:My 1998 GMC Yukon is leaking water out of the tail pipe.?
not water pump / lol its ok
Q:Looking for help picking a water pump.?
I think you may want to look at the small pond pumps and just about any nursery or home supply store or landscaping store. they may have the specs on hand, or see if they can demo one for you. some places have a display pond set up already. You also might try a small swimming pool pump and put a voltage regulator in the line and adjust the pump speed that way. maybe rig a sewing machine pedal in the line and use a C clamp for an adjuster. I love rigging thing. It may not work with a gfi plug.
Q:Thermostat or water pump problem?

Q:what are the different types of water pumps for pontiac motors up to 1981?
Actually there was two main pumps for the older ones,, one was called a short shaft,,and one was called a long shaft,,the long shaft was the most popular,and it all depends on whether your car had power steering,,and air conditioning on it,,all the ones that used the long shaft usually had air,,and power steering on them also,,also some of them had a smog pump on them,,this was the main reason they used the long shaft,,most of the smog pumps got taken off and discarded down through the years,,but you still had to use the pump that had the long shaft,,this is the problem your having,,i own a repair shop in Tennessee,,and have been redoing some old cars in the past few years i to have run across the same problem you are having,,you can have a long shaft ordered for you ,,and it will work fine,,i had to use the long shaft on the one i was redoing hope this helps some.
