On UV's and flow rates, I have a Sequence 18000 pumping through two 55 w UV's, excluding losses this could be 9000 l/h through each. The bacterial bloom was killed off and I went from cloudy to clear in less than 24 hours so they do work at that flow rate.

They can do Alan but mine have always worked better at lower flow rates than that recommended by the manufacturer ....

I could divert the flow but it would then by-pass the Giant TT where I want ALL the flow to end up going through ..

Well that went well Shocked NOT ...

The Hailea is too fast a flow for the Giant TT as was the Sequence when plumbed in initially so pondside is now `Swamp`like Rolling Eyes

I`ve managed to stop the overflow by tilting the Giant TT FOR NOW !

I will have to wait until it dries up in order to level the ground as it`s all grassed around the Vat ....

The Exit pipe return is at full throttle .. Shocked

Alan did your Hailea`s arrive with only one threaded cap Sweetie ?

I`m in and out of the Garden like a Yo/Yo atm ...

Thank`s for the pics Sweetie ... when I have to run the Hailea dry mounted I will remember which parts to buy ...

What can I bracket the UV to the wall with Guys scratch It didn`t come with any ?

Plumbing so phar Laughing

This is all dry run on my Patio (no glueing) YET until leveled Pondside Rolling Eyes

The Sand Filter male threaded hosetail is the `Original`which I only screwed back in to gauge pipe length from the Pump ....

Will the 1.5 inch pipe fit into the hex nipple hosetail I intend to fit on there ... 1st direct had a cue a mile long so I have not been able to call them yet Rolling Eyes

Ignore the dreadful mess please Embarassed Thank God it`s a `private Forum` Smile



Emptying the Sand Filter which was filled and flushed 3 X then PP`D for 24 hrs...

Guys I think I need a U-Bend trap type pipe to turn backwards from the Sand Filter scratch like this > http://www.ebay.co.uk/itm/McALPINE-SC10-P-TRAP-WASTE-40MM-1-5-INCH-SINK-WHITE-/140598979151?pt=UK_DIY_Materials_Plumbing_MJ&hash=item20bc5a2a4f#ht_675wt_905
but just the `U` part minus the threads ... where can I get one which will take 1.5 abs pipe ?

It has to be hard pipe to take the weight of the heater which will not be bracketed to anything .. IF that makes any sense to you lovely lot.

Mio

Any of the mcalpine fittings straight will take various pipe sizes, ie You can go from 1.5" white solvent weld to pushfit pipe. but not 100% sure about the black ubs pipeI have used the straight connectors many times to do exactly that.Not sure if this helps you in anyway.

My UV is not bracketed to anything but just sits on a shelf.Without problems. I have thought about usinf 4" soil pipe brackets to secure it , however my UV is circular in shape.

The soil pipe brackets should work on circular UV`s Dave ... but will not on the Pro-Clear 55 watt because of the unusual shape unfortunately ... and they are quite heavy too ...

So if I buy a U Bend 1.5 and hacksaw the threads off will it take 1.5 abs .... I have 1.5 regular waste pipe which is standard but it is much less robust than the ABS C type from 1st direct Rolling Eyes

Is your intention to glue the U bend after you cut the threads off as I believe this is the same material as push fit pipes and does not solevent weld but could be wrong.

I would just use 2 90 bends joined by a bit of pipe. I support my UV on 1 1/2 inch threaded socket unions with 1 1/2 pipe. The pipe is fixed with pipe clips.

Does that mean it can`t be glued Dave ? confused

The hex nipple 1.5 will fit inside the abs pipe ( I Hope) and screw into the Sand Filter ... I would then need either two sweep bends joined by a straight piece of pipe or better still a U Bend Sweetie to swing around to the Heater which will then run to the Giant TT ....

http://www.1st-direct.com/1-534;-mtfp-union_details.htm
If you have used glue already on the non return valve, you have a problem. If not, I would connect the non return valve to the rubber bend, the other end I would use one of these to allow you access to the NRV should it get blocked etc
http://www.1st-direct.com/234;-socket-union_details.htm

Finally the last order has been placed to 1st direct Rolling Eyes and you were right Alan Very Happy

These > http://www.1st-direct.com/1-534;-mtfp-union_details.htm
you recommended are better than the hex nipples in that they will take 1.5 inch abs pipe inside them and they also screw apart for removal of Pump/Sand Filter/Heater etc for cleaning ... Thank You Sweetie Very Happy

I will leave the under water push fit pipework and valve unglued ... but glue everything out of the water ..

The technician suggests the `U` will cause dreaded Cavitation scratch

What say you Guys ?

The PVC White pipework is not the same as abs which can be glued Dave .. I will give the U Bend Pipe a miss then because they are PVC.

Clearly a U Bend will cause problems (airlocks etc) How can I get around that Guys confused

HELP !

I have always used thread tape to seal pipe threads, but make sure yo put it on correctly. When screwing on the thread the tape should end with the tape going the way you tighten, not trying to strip it off. ie turn the male trhead clockwise to wrap the tape around the thread. Might seem obvious , hope this helps

Mio,

Trying to follow what your doing, but if your using the trap ("ubend") upside down, to avoid an air lock you can drill and tap a small hole at the high point then install a nipple that you can attach a small tube (1/8") that dumps back into your vat.

Thank`s for your input Sweetie Smile

Twas Plumbing it in reverse which caused inlet and outlet to face the same direction Rolling Eyes

Originally it looked like this >



Then this >




The 2 ,90 degree Elbow Bends forming a U Bend will come off the threaded outlet (lower black pipe in the pic) and turn a corner Norm ...

To the side and around the back to meet the Heater .... if that makes sense ? in line with the outlet ...

It won`t be facing downwards like a sink trap .... How will I get that little tap in there please ?

Any idea where I can buy one or something similar Guys ? and how do I fit it in the pipe please ?

Still waiting for the `Knife` valve Rolling Eyes and it`s raining outside ...

This is the `U Bend` which will be a little wider/longer once I add 1.5 inch pipe to join it all together before gluing .....



Sand Filter will be behind and heater in front >
