Hopefully a couple of simple plumbing system questions...

Hey all,

I'm back with what I hope are a few simple plumbing questions.....Simple for you experts out there that is!

I've attached a sketch of my very simple (I think!) water system but thought I would get some feedback and some pointers on a few of the parts.

THE SYSTEM:

A 20 gallon water tank mounted under the van where old second fuel tank was.

1/2 PEX tubing from tank to water pump to filter to shurflo water faucet.

Here are a few questions I have:

1) This PEX seems like very reliable stuff in terms of connections (from what I've read) but it does not seem to come in 3/8" interior thickness.

....So how do i reliably connect the 3/8 "barb" inlet from sink to the 1/2' PEX pipe? Also what is the best hose to come from the ink as i need something fairly flexible to get it through the wall to get to the pump. Can I use simple hose clamps? I ask because it just makes me nervous as the connections will be hidden and i have no idea if this will be reliable....


2) I would also like to have an attachment for an outdoor hose. What would be the best way to splice that off 1/2" PEX hose? Should I put a simple on/off valve that has a hose connection?


3) Any thoughts in terms of winterizing/draining the system when the winter comes?

4) Also, a question about the vent pipe that comes out of the water tank. It seems like it would open to all kinds of dirt and exhaust etc.... Is this a concern and, if so, how do I keep all that stuff out of there?!?!

5) what am I missing?!?!?!


Thanks for any advice people might have!!!

About winterizing:


I know people put anti freeze in their grey water tank. But we don't have a tank, so we have no experience with a grey water tank. We use a hose and a bucket that we empty before going to sleep.


In winter it is often too cold in Montana to use the hose though; the water can freeze in the hose before it reaches the bucket. So, in winter we use a plastic sink inserted in the actual sink. When it is about 70% full we empty this manually.


Our water source consists of three 6G jerrycans under the sink. As long as we keep it above freezing inside the van this works fine.

PEX uses it's own fittings either slip joint (push together) or crimp.

There are many different PEX fittings.

I forgot the Expansion Fittings. They require a very expensive tool to spread the pipe. I don't own the tool so I never use it.

1) PEX is used widely and 1/2" is pretty standard. You'll need some sort of adapter to go from 3/8 to 1/2. Doesn't the sink have a threaded connection?

As has been mentioned, there are specific clamps and fittings to use. Lowes and Home Depot both sell the products. You can see what they have.

You can use flexible sink connector hoses, something like this:

2) Suggest a RV outdoor shower connection.


3) Blow out with compressed air or winterize with RV antifreeze. Most here blow out with compressed air and there are fittings designed to do this. See this or use a quick connect version:

A pump is better at pushing than pulling so a mount close to the tank helps. That position puts the pump at risk for road debris.

Life is full of compromises...
