Self installed replacing old shower valve 3 weeks ago so its new.
correct Hot left Cold right.
Shower started to bring to comfortable temperature while preparing to shower.
after around 4mins shower stops of it own accord. No air problem good flow from out let on bar after removing hose to test gravity fed power of flow and it was quite strong. Head of cold tank from shower head approx 1.2mt. in attic 3.6mt away the hot same distance but ground level. What would cause the shower to stop flowing when once that is overcom by removing the hose then replacing to continue showering with no further interuption. May be a novice not trade but done enough plumbin in previously owned houses. Triton will charge if the head isn't strong enough and find no fault in the unit. How can I test the Gravity water pressure. I also have seen you can get a low pressure shower spray to replace the current one that came with the shower bar.
Many thanks in advance
