F+E tank, water level keeps rising and smells bad too.

[armyash]

Hi guys,

Last August got called out to a job where the overflow was running on the F+E, replaced the ball valve and all was well. Got called back today, the water level has risen in the tank again and overflow discharging again.

Ball valve seems to be shutting off fine, no over pumping while I was there. The water in the tank smells really bad.

Maybe split coil but the smell has thrown me off. No dead rodents in the tank either

Any ideas?

What's the colour of the water like? And is the f&e lower then the cwsc as it would need to be for it to back fill. Also what speed is the overflow flowing and how often?

The F+E slightly lower I believe from memory.

The overflow was only dripping when I got there but it had obviously had a fair bit come out before that. It has only just started happening over the last couple of days.

Could be a split coil easiest way to check would be to shuts the mains. Turn off all heat sources and drop the f and e by half place a chalk mark on the water level of both tanks tell them not to run any water inc flushing of toilets etc go and do a few hours worth of work pop back and see where the levels are.

rip it out n seal it

rip it out n seal it

That way it'll fill the cwsc

Sorry forgot to say the water is cloudy and dark and has 'slimy' bits floating around in it.

Well if it's pumping over it'll do it after a long hot run time or when circulator suddenly shuts down

I have some parts on order for other jobs there so should find out this week when i go back.

Just wondering if the cold feed is blocked and causing it to pump over if that's likely?

The pump is on 1 if that makes a difference.

It sounds like the coils gone and the system is sludged up and the cold fill and vent piped badly. Which can cause bacteria.Without trying to sound like British Gas , it sounds like it needs an upgrade to a combi with a good flush.
