No plumbing in old house...

[BamBamm]

The 3bed, 1bath, 1,400 sqft house was built in the '50s if I remember correctly.
The previous owner deleted all the plumbing except for the copper inlet. I already changed the size from 1/2' copper to 3/4 Pex and its first stop is the toilet. I plan to run 3/4 Pex throughout the house reducing down for sink connections. I am looking for the best water pressure for the tankless heater, tub, sinks, dishwasher, and clothes washer. I will be using probably a 2" drain to connect to the main sewer line from all of these.

Are there any tips you can give me to help out, I can not afford the lowest bid of 8k to replumb. I should mention there are no vents installed and I don't know where to put one.

Thank you for reading and your time,
BB

You can’t use a 2” pipe for the main drain or the toilet.

You need at least one 3” vent through the roof.

I suggest buying a good plumbing book and start studying.

I have a 4" sewer line from the toilet, I am just running a 2" line from the washing machine.

Good deal, a good plumbing book would give you some basics to follow but here on the forum we can give you pointers also or clarification.

Real good website on the basics, as well: www.hammerpedia.com

Well worth the $50 buck investment for the "inside" track!
