Installing a PEX Manifold?

I am in the planning phase of my PEX re-pipe, and have a question on Manifold placement.

I live in one-story single family home 4 bedroom 2 bath

How far can the manifold be from the water heater?

The home is about 45 feet wide running North/South. The water line in is on the North side of the home. The water heater, backyard Spigot (sprinklers) and MAIN bath room is on the North side as well, but the Kitchen, washer/dryer, and 2nd bathroom are on the South side.

I've always heard that the Manifold should be near the Water Heater, but what is near? if I put the Manifold on the North side, the longest runs would be to the Kitchen, etc...If I put it on the south side, it would be more convenient i.e. less work to run the lines, since the majority is on the south side, but it would be some distance from the water heater, and the main bath.

So, how far is too far? I don't have a large home, so I'm hoping placement isn't be an issue.

If I were to put it on the southside, then it would be a 29 foot run to the water heater, and a few feet longer to the MAIN bathroom. Yet, if I put it on the North side, then it would be a 29 foot run to the kitchen, etc..and be a lot harder to run the lines.

What are your thoughts?

Answer
I just did my home myself a few months ago... it is said that it should be at leAST 5 FEET AWAY. mine is about 25' away and the pressure is awesome.

What will happen if I accidently washed the engine of my car?

Answer
if i was you i would open the air filter and that no water has got into it. If it's nice and dry then no problem, if there is water in there then it needs to come out( and out of the inlet manifold as well if it has got that far) as water being sucked into the engine will cause MAJOR engine damage. Apart from that i can't see there being any issues.
EDIT
i don't know who has given my answer a thumbs down? If a pressure washer was used to clean it then it is quite possible that water has got into the air filter inlet. If so then it can and will cause damage. If you remember from your science lessons WATER IS NOT COMPRESSIBLE and if it goes into the cylinders the it can easily snap a conrod or damage piston rings or valves as you turn a cold engine over to start it!
