Pump plumbing porn

So I’m in the process of setting up a res or 2. Need ideas on what pump to use so as the title suggests show us ya pump and plumping setup for those that are using them.

No submersibles

 

[R3za92]

This is a similar idea to what I’m leaning towards

that seems overly complicated, I am just running a submersible

Pressure Pump 240V (11.3L 45PSI) SEAFLO 33 Series

Ultra compact 11.3L/Min 45 PSI 240v Pressure Pump uses duplex diaphragm design to deliver flow and pressure comparable to much larger pumps. -- Features: Sealed pressure switch automatically starts and stops pump when discharge valve opens and closes. Self-priming so pump can be located above...

Seems like a solid pump, low flow high psi. Can pair it with pressure compensated drippers get exact doses and a netafim y filter..

Can get a bit fancier add a pressure tank to it and solenoid + controller then run multiple tents from same res/pump

 

[Billygoat]

Agree, look at all the reducers and joiners... combined with a bunch of electrical stuff all nearby, looks like a recipe for disaster.

I got nothing. Old school here where submersibles and aerators are suffice. No need to fix what isn't broken.

Interested to see what you come up with though, R3za.

I’m using smaller res’s and submersibles add heat I don’t want to deal with to the res. So in-line pumps are what I’m going with.

From reading up you need a manifold above the res with a bypass back to the res to stop siphoning or gravity draining thorough the pump.

I’ve bought a similar pump but Higher psi and more flow.

Electrics can easily be moved. That also isn’t my build I wouldn’t have the transformer that close to the res.

Wouldn't placing the pump higher than res stop that? that pump is self priming think its 3m above source.

Also how long are you planning on running the pumps? I had a small aquarium pump with 13mm outlet running in a 35 litre res 24/7 never had heat issues in the res.

Running 60l res at this stage. Had heat issues before from submersibles also they gunk up and I can’t run a pre pump filter.

They self prime bit they can also siphon if there’s no pressure release at the highest point. Where the pump is is less important than where the outlets are and they’ll be below the res level majority of the time.

Foot valves come in handy at keeping a system primed. Well, at least the lowest point in the rez and your pump.

When designing the system, keep in mind to avoid creating spots in the system where air locks can form/hold. Made that fuck up just recently myself, was wondering why my rez return wasn't flowing.

Right never had my submersibles gunk up that badly, is it your tap water or organics in the res?

How would you release the pressure from the pump to stop the siphon in the above pic? open the recirc valve in that pic? that would be annoying.

You could get a single or multiple solenoid controller for the inline pump, have it after the pump so when it shuts off no chance of anything siphoning. But you wsould also need to get a pressure tank for the inl;ine pump to stop it cycling and keep it alive fore a decent amount of time. which will also really be quite expensive in the end.

 

[frankreynolds]

In regards to the siphon can't you just poke a hole in the feed line at the highest point run some 3 - 4mm spaghetti tube back to res?

Yeah resirc valve would be constantly cracked for both a pressure bleed off so pump doesn’t cycle and a anti siphon point. Also acts as a waterfall to aerate the res.

Accumulator tanks are like <$50 and I could easily diy one. Hardest part is making the bladder and getting it watertight. Hoping I don’t need one with the bypass back to the res.

Solenoids would also work but complicate things a little more and add another point of failure.

Most of it will be hardline pressure pvc. Only part that will be standards irrigation pipe will be the 4mm feed lines from the manifolds.

 

[frankreynolds]

It just seems counter productive using an inline pump which you would use for the higher psi and then bleed that pressure out tho?

 

[frankreynolds]

I personally wouldn't worry about irrigation solenoids failing if you buy a decent quality one, same with the controller.

 

[frankreynolds]

You could also just have a small 19 poly area at the highest point so you can add that suction break the fitting would be cheap

 

[frankreynolds]

I've also had better luck with a cheap aquarium wave maker in my 100l res on 24/7 to mix things around by far the best

 

[R3za92]

Only bleeding the excess pressure. Essentially you open the return valve only as much as you need to stop cycling. All the feed manifolds are pressure reduced to 100kpa anyway which the pump easily exceeds.

I’m not trying to make a pressurised system if that makes sense because there’s no off taps on the feed end.

 

[frankreynolds]

right just seems like inline pump isn't the best then.

Just thinking about it if you do choose that pump, and you use netafim pressure compensated drippers like https://duralirrigation.com.au/products/netafim-pcj-on-line-pressure-compensated-drippers

you could just run the pump with a simple timer when it turns off won't be anough pressure in the line to turn those drippers on.
