I am getting a tank fitted into van next week then i am doing the rest fitting the pump/controller and di etc in the van.

I going to use john guest push fit fittings .. can you get a 1 inch fitting for the tank? if not what would be the best option for the inital tank outlet socket.

It's a simple reducer like the ones you get with Hoseloc.

when putting plastic fittings into the brass thread of the tank make sure you use some ptfe tape and make sure you dont cross thread or over tighten them, as plastic will thread or crack easily causing leaks.

being a plumber, one other reason not to use plastic is incase you drop something on it it will break and crack off, leaving you with a van full of water and an empty tank, plastic over time wears and can crack as brass fittings wont. not ideal if you use warm water in the tank as this will cause the plastic to expand and contract which can also lead to leaks.

But if you use brass and drop something on it you're more likely to split the tank than the fitting.

Fittings are cheaper to replace. I'd go with plastic in this particular case.

Personally I use one of these:

not at all,  because there is a brass thread already in the tank and that part of the tank is reinforced, so wont break easily, to break that you will need a very heavy force. all plasitc part are only made from a thin plastic that.

[traps7]

Fair enough, but it would be best with a tapered thread.

yes tapered threads are used in some plumbing for high pressure work.

on plastic pipes due to the wedging effect of the tapered thread, extreme care must be used to avoid overtightening the joint. The overstressed female fitting may split days or weeks after initial fitting.

could someone let me know if this fitting would be ok to screw onto a shurflow pump like the one in sunshines video. http://www.jtmplumbing.co.uk/john-guest-speedfit-fittings-167/john-guest-speedfit-bent-3244.htm .

Thanks 

[R.C Property]

Yes that will be fine to use, just watch out for cross threading.

[dave0123]
