Big Problems fellas

[TopTrumper]

I installed a triton power shower today and then found out i made a booboo.

I took the cold water feed from the tank in the loft, which seems right.

I then took the hot feed from the hot water tank, straight up into the loft and dropped it back down parallel with the cold water feed.

turned shower on and no water whatsoever came out, just the shower pump humming away.

Reference the hot feed i was not that sure to start with anyway so i rang a gasmate of mine who said if it has a pump you can take it from were you like...after reading instructions it says it has to be level with shower (according to diagram)..

What i need to know is?

Is it an absolute must to alter my pipework?
also, why did no cold water come out of the shower at least?

Im back on the job tomoz guys so speedy answers would be great.

PS i am a spark who arived at house expecting to install electric shower

 

[breezer]

how about fitting 2 non return valves at scource, and isolation valves near shower, i guess their is an airlock

or follow instructions

or tell person conduit will soon rust and its not a job for you

HIgh part of pipe needs a manual air bleed point, though I would have though CW would have come out if not the hot.

Thanks for speedy replies fellas.
A bit more info.

Shower model
TRITON Thermostatic power shower AS2000XT

From the cold tank in loft, a pipe was running downwards, i think it was for the bathroom sink, i teed off this for the cold feed (after i teed off i immediately put a 15mm isolating valve on)
After reading further in manual i think this is a nono???

From the hot tank i teed off at the top of the tank between the pipe running down and the vent that goes upwards to the cold tank, again after the tee a 15mm isolating valve installed...

I never dismantled shower from pipes to check if any water was coming out, i am going to do that in the morning....
Any more input would be appreciated fellas, thanks

Sorry for stating the obvious but did you check you had opened the isolation valves properly, and, not that it necessarily changes things, have you got the arrows on the valves pointing in the right direction of flow?

By teeing off the top of the hot tank on the horizontal run to the tee which spilts the DHW supply and the overflow/expansion outlet you therefore should have given the shower supply sufficient primacy for hot water but you say you had none. Does this happen with power on?

Also by connecting to the cold water tank (which should be at least (230 ltrs capacity for most showers of that type) you should have a reasonably balanced flow, but you say you have no cold flow either. Does the shower have negative head capability. Not necessarily an issue, but if a lack of head is the cause it might explain your problem. Its just a thought.

possible air lock and gate valves should have been fitted to this unit not ballafix

 

[meldrew's_mate]

When you take the shower off the wall open each isolation valve in turn to flush pipework and purge the air out. Make sure the feed from the DHW cylinder goes down before it goes up or it'll keep airlocking and you'll fall out with your customer rapido.

Sounds like air locks. The 15mm isolating valves don't let the air get back up the pipe and there is insufficient pressure to force the air down to the shower.

You need to let the air out of the pipes at a high point - loosen a nut temporarily.
Once the pump is primed it will go.

Thanks fellas,
yes valves was open,
just one more thing,
i used the valve like this

I have read i need to change to full bore, can anybody post a link to full bore?

 

[dal5band]

just type "gate valve" into Screwfix search.

night

 

[ChrisR]

I think you meant "full bore" ?? http://www.screwfix.com/app/sfd/cat/pro.jsp?id=13103&ts=73529

 

[Paul Barker]

That's good value and it does gas too? Must order a bunch.

 

[ChrisR]

The peglers ones are better. I think the cheap ones may only have an O ring on the gland instead of something you can do up. Only really seems to matter on CH

 

[TopTrumper]

Just an update fellas.
Went back to house to sort this power shower out.

Changed my ball valve for full gate valves.
took the shower off the wall and opened valves, water was oozing out both pipes just lovely, did this procedure a couple of times..

I then remounted shower and turned the power on, the pump started up but still not a drop of water to be seen..

The customer is ringing TRITON customer service, can anybody think of anything that i may have missed???

 

[dal5band]

Someone had a problem with none return valves the other day on here - the water pressure was not enough to push past the valves in the first place. He needed the water to run to turn on the shower motor.

See if yours has non return valves on the inlets, in the instructions.
The solution was to remove the NRVs.
