Only a Falang ...


Recommended Posts

An absolute waste of resources, could eliminate all the valves and fittings, brackets etc and it would have been better located directly in front of the house and not in the garage where it might get hit by the car. Should have been installed by a Thai "plumber"  to ensure a good job ????????????

Jokes aside looks good.

Seriously though, why all the valves ? Can't for the life of me work out what they are for !!

Normal practice would be 1, possibly 2, isolation valves for your domestic supply and then small ball valves at each outlet to isolate that locally if required....

Seems like someone trying to be clever for the sake of being clever !!!

Looks like each facility has its own supply, a bit over the top but no problem.

I'm going with swimming pool pump/filter installation. 

A man who reads the Swimming Pool forum methinks, Carl has a long thread there.:smile:

 

I note a small Thai "feature", the use of a PVC end-cap as a pipe support, bottom right of the image :whistling:

The valve set up is way over the top for just a pool...

But Auto Chlor can be used for domestic supply too I guess, as can that sand filter...

 

I'd be looking to box those valves for neatness and protection...

The return delivery pipe system back to the pool is really good especially with the bypass for the chlorinator.

 

However the suction side needs a bit of a rejig.

You have sentenced the poor pump to a life of being constantly being in the repair shop.

It is close coupled to adjacent fittings on the suction header which by the way is to small for the application resulting in high flow rate . Good practice dictates there should be a minimum of 5x pipe dia of clear pipe i.e. no valves fittings etc prior to the pump.

 

When i used to sell  pool pumps and there was a warranty issue we always asked the customer to supply a photo of the installation if it was installed as per your setup I would have voided the warranty.

..and if those Qcon fixings are no good the whole lot is screwed.

 

I didnt appreciate the lekky panel was so low, you could have sat it on a chair

Have another look. ?

The pump manufacturer said a min. of 45 cm of straight pipe section into the pump...which I have.

An American pool forum (don't like TV pool forum as not very friendly) said that these days you don't even need a long straight section into the pump because the skimmer tank at the start if the pump is large on modern pumps to compensate for small inlet straight sections.

 

It's like the main drain, or 2 for safety. Why have them? If you read other progressive pool threads in the US seems that way. 

 

And the electric bonding. Why have it?

Anyway we differ in opinions.

And I've gotta wrap some black tape  around a joint to make it more authentic.

Firstly my apologies to Carl for sounding a bit harsh but it if it prevents others for making mistakes it will be of some good.

Your set up will work  but there will be an increase in power consumption and a shorter pump life.

A good read but some what technical  is a publication called 36 ways to murder your pump, published by Crane fluid control it is in pdf or as an e book.

Good luck Frank

Must have been the angle of the original photo my apologies, good luck with your commissioning. F

No worries....I blame you and Crossy for all the valves. ? 

One thing you all missed in my previous swimming pool forum posts is that I had all the  rhs valves round the wrong way. Until I had a stuck one and pulled it to pieces did I notice the inlet shape was different to the outlet, then noticed a small arrow on the valve bottom.

When my panel door arrives from China the place will be closed off.

Why will there be an increase in power and a shorter pump life, that is nonsense?

Think cavitation and impeller erosion.

Nope, the controlling influence on water entry into the impeller eye will be the strainer basket on the inlet.
