Hi,

Which fitting are you referring to?

The drain plug on the outside, or the hot water discharge on the inside?

Any chance of pics of the fitting you are talking about?

Is the tubing in the camper gray or blue and red? This helps tell us what type you have.

Here is the blue and red tubing of the newer Pex. Are you after the white 90 degree elbow on the bottom or top as shown in these pics?

The size in these pics is 1/2" Pex tubing. Coming out of the top of the HW heater is a 1/2 NPT check valve that then screws onto the white female elbow which has the thread pitch like 1/2 NPT but is not tapered, it is straight running thread and has an inverted chamfer inside so it can seal on that chamfer. see below





The inverted chamfer looks like what is in this pic.


If all of your tubing is gray, that is a little bit different then the newer PEX

Thanks for the help and pictures John.

Water tank fitting is at the outlet going to the pump. (tubing shows 5/8 OD printed on it)

All of the water tubing is grey, also looking for a quick connect or 'shark' for the inlet to the hot water heater, I broke a fitting at the inlet tee of the HWH.

This tubing is smaller then the whats at the water tank and pump inlet and also smaller then what's coming into the camper at the city water inlet tee.

Here's some pictures hopefully. Thanks for any help. Greg & Patty





Broke fitting shown in this picture & the two different sizes of tubing at the tee before the HWH tee

Better explanation:

Trying to do (2) two things at once really...

Add Hot Water Heater By-Pass (broke fitting at inlet tee)

Add Winterizing Kit at pump suction, but not enough room
between the tank & pump. Can't move any further apart.
Pump suction tubing is hard and crimped fittings are tight,
I was going to replace the tank elbow 90 and make up the
new hose (line) length for the new valve kit and coupling?

Not sure if you ever got this fixed, but all the fittings you should need are available at Lowe's. That 5/8" OD pipe is polybutylene. Most 1/2" shark bite style fittings should fit over it. That 5/8"OD pipe is just 1/2"ID pipe and you can replace it with 1/2" PEX pipe. You may have to cobble something up, to replace the tee though. Also, that 90 degree fitting in the fresh tank should be threaded. If so, you should be able to find that at Lowe's also. I would replace that gray PB pipe with some reinforced vinyl tubing.. That is what Sunline used on their later-model campers.

Hello and Happy Spring... Our camper is about 1 1/2 hours away...

Does anyone know what size water tank fitting threads are at the tank outlet going towards the pump.

Here's a picture hopefully. Thanks for any help. Greg & Patty

Hot Water Heater By-Pass and broken fitting at inlet tee fixed with 'shark bite'.
Also the Winterizing Kit between tank and pump is also installed & working fine.

We'll be ready for next winter, but now it's time to enjoy the summer camp first.

If you can post pictures of your "fix" it would be helpful for others in the future.

JohnB has been very good at doing this and it is amazing how often his (project pictures) are used over and over in post!

Shark bite's will join pex to the gray stuff or gray to gray. The plumbing fittings are standard plumbing sizes.
