Thanks. So the manifold might look cool but it's not needed. I intend to get 1/2" tubing.

Started Pex replacement today

Restoring my 1976 and this week put air to check for leaks. Wouldn't you know the previous owner didn't winterize so I found several splits.The main one was close to the tub mixing valve and naturally difficult to get to. Decided to replace the valve and fish the new pex in.Took most of the day because you can't get to anything. It was difficult but forced me to do the rest. If any one watches the Christmas story the guy working on the furnace with bad words may sound like me. We will see how this goes.

I would stick with PEX and Ts. Keep it simple. When I pressure tested the Bambi, all the leaks were in the brass PEX to MIP or FIP fitings. All the crimp rings on the Pex were perfect.

Thanks Tim. Looks like I can order what I need for this job in a month or so. Getting the floor repair and outriggers done first.

Pex manifold

Can I use a copper Pex manifold that has a 3/4" input and 5 of the 1/2" ports? It is mainly the 3/4 input line I am wondering about.

Not sure if you received an answer. its a ribbon type "heater" that you wrap around your pipes and plug in. there normally is a thermostat connected that turns the system on at freezing temps. it would mean that your trailer would have to be connected to power all winter though.

Pex manifold

Alan, I hope all is going well with your pex replacement. just a suggestion. I wondered about using the pre made manifold. As I got into the process. And ran the various hot and cold runs back to the rear access so I can see any joint leaks I decided against using the manifold and made one out of lots of tees and put the connections where I needed them. The 3/4 inch in and out cause too much connection problems for me. Also you want one output to be horizontal to the drains so everything drains out. I took ours to Fort Mountain last weekend for the first time out to check all plumbing and everything worked well. Good luck on your project.

GUESS I asked the manifold question twice. Sorry. Saw a 3/4 in with 5 1/2 outs and figured it might be a simple set up, its about 10 bucks.
I am ready to start putting inthe pex, got both faucets set in place.

anything special to look for in crimping rings and tool? I see copper rings available pretty cheap. If I buy a bunch of tees and rings it will sure be less than going with all shrkbite connectors. $$ is an issue right now
( I mean always..)

Alan,
I bought a crimping tool from Lowes that has 3/8,1/2, 3/4 and 1 inch rings. It was around $100 but got it on sale for less than$75. May have been a close out model. I have only used the 3/8 and 1/2 but I like it a lot and never have to do over. The shark bites are expensive and I only use those types when going from the PB to Pex. I'm looking to buy a bunch of couplers, tees and elbows so I can quit going to Lowes to buy. HD rarely has any Pex in there mess for Pex. I want to transition out of the PB as soon as I can and also need to do some water lines around the shop. If you find a good source for the fittings, let me know.
Joe

I am an Ebay nut and I see lots of Pex stuff on there. Often the crimpers for 20-30 a piece and the fittings in lots at good deals. Usually someone who bought too much, or a dealer who sells close outs. I went to HD just now and they are pretty limited on what they have. The guy told me to stick with the brass connectors, and try to do as many connections as I can beforehand. I did not think of crimping on short lines for the faucets, inserting the faucet body and then attaching the tee from below. It shows just how much of a newbie I am for plumbing. DUH

Alan, Go to Lowes for most of your things if not on EBay. They have more things for pex.Some things you may want to consider. In doing my 1976 this is some things I found.Lowes has--1/2 inch pipe with tabs used for shower heads that screw to the bumper for the inlet when you put a garden hose fitting. 1/2 inch pressure reducer,1/2 inch check valve,1/2 inch pop off valve. HD doesn't. 1/2 inch pipe that hand tightens to faucet end and hot water fittings. Kolbot tools makes a pinch clamp tool instead of using compression rings, They get in closer and I didn't have any leaks.I used the toilet cut off valves to make the low area drain and two sink supply lines through the bottom . you need a line from the pop off valve incase over pressured. Buy contractor packs of tee as it takes quite a few. Lowes has a better selection of brass instead of black or galvanized While you're on a roll add a valve and hand sprayer in the back to rinse feet at the beach. Soon I will try to learn how to add pictures and some of this may made since

I ordered a bunch of fittings: tees, couplings,elbows, crimp rings. All from Pex Universe.
Their prices were less than half of what I found at Lowe's. Home Depot had little if anything at the one near my home.
I will buy the tubing at Lowe's or HD, and use a few gator or shark bite or whatever they have fittings for the water heater.
Now i need a crimper. Saw one hand made by a seller on Ebay that looks promising. Lifetime warranty from him also and many sold.
Ready to get started as soon as the weather is a tad warmer..
