Retirement and forum shutdown (17 Jan 2022)

Hi,

John Howell who has managed the forum for years is getting on and wishes to retire from the role of managing it.
Over the years, he has managed the forum through good days and bad days and he has always been fair.
He has managed to bring his passion for fish keeping to the forum and keep it going for so long.

I wish to thank John for his hard work in keeping the forum going.

With John wishing to "retire" from the role of managing the forum and the forum receiving very little traffic, I think we must agree that forum has come to a natural conclusion and it's time to put it to rest.

I am proposing that the forum be made read-only from March 2022 onwards and that no new users or content be created. The website is still registered for several more years, so the content will still be accessible but no new topics or replies will be allowed.

If there is interest from the ITFS or other fish keeping clubs, we may redirect traffic to them or to a Facebook group but will not actively manage it.

I'd like to thank everyone over the years who helped with forum, posted a reply, started a new topic, ask a question and helped a newbie in fish keeping. And thank you to the sponsors who helped us along the away. Hopefully it made the hobby stronger.

I'd especially like to thank John Howell and Valerie Rousseau for all of their contributions, without them the forum would have never been has successful.

Thank you
Darragh Sherwin

RO on overdrive

( My RO unit went into over drive and spat out more than 3 times the water it usually dose.
I normally put it on last think at night and by the morning i have about 5 gallons. This morning the 5 gallon water butt was full. The 15 gallon over flow was full and about a good 5 gallons had over flown onto the floor, through the ceiling (i'm in the attic) and onto the carpet below. Through this ceiling and on to the ground floor. Nightmare.
The water pressure is the same. The TDS is fine and the membrane hasn't broken down.
How could this happen?

This is the second major leak i have had with the last one costing several thousand € to fix. New ceilings, carpets etc. The problem that time was a snapped plumbing fitting that was a manufacturers fault which left the full flow of mains water flood the house.
I have been told that this was the last straw and the fish have to go.
It looks like you will see some fish for sale in the coming days. :(

Any ideas what went wrong with the RO?

Sounds like membrane gone. check the TDS if it's over 40 then it's membrane.

platty252 Dont know where you live But it seems to me you have a problem with mains water pressure build up at night time or water surge its quite common very little water being used in the early hours the preasure can build up. This is what probably the failure of the fitting on the last incident .When the preasure builds the weak joints fail or in your case the valve was open with 1.5 bar going through then in the early the preaure raised to above 3 bar so more water pushed through.
You might need to look at installing a pressure reducing valve in your mains incoming.

@ Russell; the TDS is 1-2 so the membrane is fine.

@ paulm; That makes sense. Although i have been doing it this way for over a year with no problems. I always get roughly the same amount of water in 8 hours.
I will change all the cartridges, check all the seals and have a look at some valves that will only allow 1.5 bar of pressure so i dont get a build up and another flood.

After much groveling the fish can stay. Just as well since i arrived home with more fish yesterday.

Thanks everyone.

THATS A BIG CHRIMBO PRESSY YOU HAVE TO BUY HER INDOORS

:laugh: :laugh: :laugh:
I have seen this happen before when I did callouts to flooded homes . Pressure raises at night and pop something blows. All we could is stop the flow of H2O and advise the PRV( presure reducing valve.) Happy to see your keeping the fish. ;)

The rooms that need redecorating have already been pointed out.
I even went out yesterday and bought a generator to keep the house powered up in case this ESB strike goes ahead. Which sounds more than likely.
It's really for the fish but if she gets heating on and the TV she will be happy.

my RO unit has a tap connector to an outside tap. The worst that can happen is the tomatoes drowning :)
Maybe something you want to look into to keep herself happy

I am using a tap connector. But it is in doors.
It is getting to cold outside to use an RO unit.
If i remember correctly if the membrane gets to 4c or bellow it will start to brake down.
Besides it's a long hike up hill to get to the attic.
My poor little legs wouldent cope.

Hi Darren.
I have mine rigged up under the sink unit inside the house.
I got a splitter for the mains where the cold water goes to the
wasking machine. It is in the shape of a Y.
Simple idea. One feed goes to the washing machine and other goes to the RO unit.
I drilled a hole outside to a 40gallon container which collects the RO and over flows down the mains.
I will show you when I drop ove what I mean.
Will try for Wednesday if that suits.

Wednesday is fine.
I just dont want the hassle of dragging water up to the attic. Although it is better than sending it down from the attic via the floor.

Hey Darren

Sounds like the black washer around the ro membrane has go pinched when you were putting it in I happened to me last year and did not become apparent until the pressure change in the local supply. Bummer about the damage they cause when they do go. Floods are the norm in my shed they are calling me nowa at home now

The membrane hasn't been changed in the last year.
I only use about 5 gallons every 10 days or so.
(small marine tank)
When i strip it down i will check all the washers etc.
Cheers Nowa.
