Is it possible to make a template with wood a place a small piece in the template called a closer to finish, then cut your pipe to the size of the completed template. This is how pumping systems are made in the marine industry. Just an idea, hope it helps

I cut 2 more inches off the vertical white pipe in this pic but the angle is still too steep Guys Sad It does not seem to be reducing IF that makes sense Embarassed



Template Sweetie scratch can you draw a diagram of what you mean confused

Make the run in wood as if it was the pipe, This may take a number of pieces, screw or nail them together instead of glueing.useing a smaller pieice for the final closing piece. When finished it could be made of several bits and will be from your PBD to your pump suction.and will replicate your pipe with the same angles and final lengths. Once completd the pipe can be made exactly the same as the template but with much fewer piece. Hope this makes sense

Mio, do you have another 45 degree bend? if so, cut a piece of pipe 100 mm long, dry fit it in the existing 45 degree bend, don't bother with glue as it is suction and will not leak. Now place the second 45 bend over the pipe, if you turn this bend on the pipe, you can produce any angle you want to get out of the tank/pond/vat, add a length of pipe suitable to reach the top of the tank, job done. If you don't have a second 45 bend, you have my sympathy, sorry.

PS, the friction loss is negligible.

I don`t have another 2 inch 45 degree elbow bend Alan but could fit the one-way-valve into the first 45 degree elbow thereby reducing at that joint to 1.5 by fitting a 1.5 degree elbow there instead of reducing at the inlet side of the pump ... IF that make sense though scratch

From RBD to the `bend`and one-way-valve it can be .. but not thereafter because both inlet and outlet of the Lowara Pump will only take 1.5 inches as will the Sand Filter/Heater/UV etc.

This will fit into the elbow just prior to pump inlet then take 1.5 to the inlet http://www.1st-direct.com/rainbow-1-534;-234;-nonreturn-valve-2-lb-spring_details.htm

If I place 2 blocks atop the table the Pump will be sitting on it will take the pump 4 inches above the Show Vat which is then 10 inches above water level... but will make the angle?

Will that be ok ?

Alan do I not need to glue the pipework ? I would be fretful of these coming apart if not glued Sweetie affraid although they do fit snugly?

The Sweep elbow bend made the angle more precisely than any of the others which is by far the hardest part out of the way Rolling Eyes




I couldn`t fit all the 1.5 due to not having enough 1.5 elbow bends Rolling Eyes

What a bl**dy Nightmare getting the Angles and Measurements just right have been Embarassed

I could not have done it without all your Help you Lovely Lot Very Happy

Thank You for taking the time and trouble to do the diagram for me Sweetie.

I didn`t have enough 2 inch 45 degree elbows Alan so had to revert to the Fernco sweep bend which worked Very Happy

The block height atop the table is precisely 33 inches which is the height of the Show Vat .... the Pump is on top of that which should line up with the Sand Filter nicely ...

Only the 1.5 pipework to do now which perfectly fits the lowara inlet/outlet fittings but a tad too big for the Sand Filter hosetails atm... Rolling Eyes

Mio is that the nonreturn valve next to the pump before the bend. It might be better to fit it at the water surface, so when you slowly fill the pipe through the filter basket it will ensure that the pipe is completely full of water and will therfore prime easily. Just my thought

Quite right Dave, as you have it Mio, you will have an air gap between the water surface and the NRV. In theory, after the pump has been run successfully for the first time the pipe should stay full but I somehow doubt it would.

A Friend suggested I use the pond vac to suck from the RBD past the None Return Valve .. and then attach the Pump scratch

Would that be a viable option OR ?

Go for it. Hopefully it will stay full of water after you clean the basket. Also that you don,t get any debre stuck in the non return valvw. Good luck

I will give the Vat base a good vacuum before putting the cover on which should keep any debris out Dave ... Very Happy

The difficulty I am having now is getting the 1.5 abs pipework to fit the Sand Filter /heater/UV hosetails etc Rolling Eyes

I might run the UV off a smaller pump separately Guys ... scratch

Blo**dy Pipe Phittings Laughing

Will these work as Hosetails on the Sand Filter and Elecro Heater please Guys Question http://www.1st-direct.com/1-534;-hex-nipple_details.htm

I have sooooooooo many parts that have not worked now....

Partly my fault for not getting the measurement across to the sales person over the phone Rolling Eyes

I have decided to play-it-safe and `JOIN`the pipe under water to the one-way-valve ... Will 2 of these 2 inch sockets do the deed please ?

The first is will fit your filter/heater but it will require a bend or socket to connect the pipe. Personally, I would use one of these so you can disconnect the unit easily.
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

The threaded socket unions won`t fit the pump inlet/outlet threads Alan I asked the technician over the phone scratch but the 1.5 inch abs pipe fits inside the white inlet/outlet fittings perfectly. Very Happy

What if scratch I fit the non-return valve to the Fernco sweep elbow bend directly off the RBD scratch then fit the 2 inch pipe connector which the valve should fit into and continue up to the Pump using the same white elbow bend off the 2 inch abs ... then reducing it with this > http://www.1st-direct.com/234;-1-534;-plain-reducer_details.htm which I have here .... scratch then 1.5 abs pipe to Pump inlet .. take a small piece of 1.5 UP from the Pump outlet .. add a 1.5 90 elbow then on to the Sand Filter which has female only internal threads for hosetails .. as does the Elecro Heater ... whilst replacing the corrugated hosetails with these smooth types http://www.1st-direct.com/1-534;-hex-nipple_details.htm

Currently ALL appliances are fitted with these in white due to the previous corrugated Alfagoma > http://www.ebay.co.uk/itm/2-BSP-Male-x-50mm-Plastic-Hose-Tail-/120658636109?pt=UK_DIY_Materials_Plumbing_MJ&hash=item1c17d0ad4d#ht_1618wt_905

Does that make sense to you Guys Embarassed and will it work please ?

These are for fixing a socket or a bend to. I have used them on the suction side as you intend to but I would not trust them on pressure side if using a Jubilee clip.

Thank You Sweetie Very Happy

I will buy the last lot of fittings from 1st direct tomorrow and PRAY the Fab Weather holds for a few more days at least....

You have both been of Invaluable help to this DIY/DID throughout this Plumbing refit Project Very Happy Thank You so very much Guys Very Happy

I`m about to switch over to the Hailea which I will run inside the Vat for now until the Entire Plumbing Re-Fit is completed ...

The UV will then stay offline until I plumb it seperately ....

I don`t want 14000+ lph pumping through it Rolling Eyes

Can I fit a 1.5 Fernco sweep to the hex nipple I will be screwing into the Sand Filter as a hosetail ? Both inlet and outlet face the same direction .... and Thank`s Guys you have been Troopers.
