This line is definitely too small. Ideally, you would need a 2" pipe, reduced to 3/4" to give proper pressure to that many homes.
Most single family homes have 1" coming from the street and reduced to 1/2" throughout the house.
Water Main Size - Posted by Marty
Posted by Marty on October 25, 2004 at 20:18:32:
Hello All,
I am looking at a mobile home community that has 52 spaces with room to add 10 more. The water is city water. I am doing my DD now and the current owner told me he replaced half the water lines in the park. He told me he used 1/2 inch black plastic pipe rated to 100 lbs. pressure per square inch for the main. (1) Is this size water line sufficient for this community? It seems a little small to me. (2) Generaly speaking are the laterals the same size as the main in a MHP? (3) As far as the water lines are concerned, what else should I be taking note of?
Thanks for your time and input.
God bless,
Marty

If I were you I would check this out, I am not a plumber but I cant imagine 42 homes being serviced by a 1/2 inch main. I think that would be impossible, but again I am no expert. I think we have all been in a house one time or another where you get scalded when someone flushes the toilet. Can you imagine 12 homes showering and 5 flusing the toilet at one time? And that is not even counting who is doing the dishes and who is watering the lawn. Do a little more DD on this one, I think you will uncover something different then what the owner is saying.
Now having 1/2 inches servicing that many homes seems impossible to me. I would bet that he has larger main lines and then they T off into the half inch and then go into the homes. If he is absolutely adiment about there being a half inch main, look at it yourself, go lift the main water meter cover and take a look. (assuming it has one)

In my park(47 lots) the water main is 4" with 3/4" tap on each lot. The 1/2" main line is way to small, check your city or county code. Good luck!

It seems small to me too. Ask the tenants about water pressure at peak times, if you can. A peak time would be 6:30-8:30 AM weekdays. Pressure will be reduced during peak times if the line is too small.
My park is about the same size as the one you describe. I have three lateral 2" pvc lines reduced to 3/4" at each site. Never had a problem with that but I don’t know how much smaller would be sufficient.
