Then I have be in touch with realtors that have a existing manufactured home on a lot that was Perk Tested 5 years ago for a 4 bed room, but the home is trashed and I want to put another 3 bedroom manufactured home on the same lot,Now it will only Perk Test for a 2 bedroom?
How can this change just in 5 years, Or is this normal...... Is their a time limit on "Perk Test"?

They use bedrooms as the standard because that is usually an indication of how many people will be living in the house. Bathrooms are irrelevant. We all have seen public restrooms that have 2 stalls to service a line of 25 women!!
And, often, if a new building is being erected, a new perk test is required. Standards for time limits on the perk change (maybe from a 30 minute to a 20 minute at 10 inches deep perk hole or even the depth of the hole can be changed with new regulations). Also, the number of bedrooms will dictate the size of your septic tank. The more bedrooms, the larger the tank must be.
You also have to consider if the siting of the new structure is going to be in a different spot on the property, where's the well, if any, etc. And, drain fields do fail many times - so, a new perk tests is required.
Some states or individual towns require an alternate drain field site with the initial perk approval in case of failure of the first site after some time (usually happens to a border line passing field). It doesn't just come down to "does the water drain into the soil away from a water source?". (Boy, do I love to talk dirty sewage or what?

)
Actually, I worked for a Massachusett's DPW in engineering and handled all of the perk tests results through our Dept. of Health. So, know a little bit how it all works.
