HW Cylinder Replacement

[wrecked_24_7]

I had to do a HW cylinder swap for the first time the other day, when i came to making the connections i used ptfe and water hawk. I had to empty it 3times and ammend the feed connection as it kept seeping. I thought i had sorted it, but have just had the customer ringing saying its seeping. I have put ptfe and compound on it and it still seeps. Please any ideas what to do? Also i never noticed this but apparntly there was a pipe near thefeed and expansion tank that every now and then throws out a cup full of water apparntly. Im assuming this should have a bleed valve or similar on it, apparantly it never spat water out before i did the swap, but now it is, im assuming maybe its just air getting caught and escpaing, but il have a better idea on that when i go round and have a second look. Please any thoughts onthat too. But my main issue is with this seeping connection. Will i have to just use like a whole roll of ptfe and loads of compound i dont know. Please any thoughts. Thankyou

"Also i never noticed this but apparntly there was a pipe near thefeed and expansion tank that every now and then throws out a cup full of water apparntly."
Vent pipe or warning/overflow?
If the former check stat settings if the latter maybe f+e no longer big enough/water level set to high.

Hi Wrecked 24-7, the threads are parallel and not tapered so its hard to get a watertight seal. Try Loctite 55? and LSX. Wrap the loctite sealing cord around each thread then smear the lsx on. This should do it.
P.S. also repeat on immersion thread

Sorry for my ignorance, LSX??? compound?
